01 / Background
Rain Water at Spring Festival Had to Link Nature and Family
In 2026, Rain Water fell on February 18, the second day of the first lunar month, so the solar term had to be introduced amid the Spring Festival mood. The creative focus shifted from flowery descriptions of spring rain to seasonal signs, farming and ordinary people's lives: the film had to show “otters lay out fish, wild geese return, plants begin to sprout,” and also connect the solar term with family ties.
The opening uses the eaves of a historic building and red lanterns to show it's New Year, and then a misty, rainy lake, a canyon stream and terraced fields carry “water” across the landscape; the film then shows plowing preparations, cooking porridge and a visit to the wife's parents, grounding the changes in nature in scenes of daily life.
02 / Creative Highlights
Turning Seasonal Signs and Folk Customs Into Recognizable Actions
01
Lanterns Set the New Year Scene, Rain and Mist Link the Landscapes
The red lanterns in the opening stand out sharply against bluish-gray historic buildings and light rain. Boats on the lake, willow branches, streams and terraced fields follow one after another, all full of moisture, linking Spring Festival with Rain Water in just a few seconds.
02
Turning the Three Signs of Rain Water into a Chain of Visible Actions
An otter carries a fish ashore, leaves it on the bank and goes back into the water; a flock of geese flies past an ancient pagoda; up close, plants sprout and grow, each matching one of the three seasonal signs in the narration. The film teaches through animals' actions and plants' changes, giving the short a storyline you can see.
03
Expressing Family Ties Through a Clay Jar and a Welcome
The family segment shifts the eye from landscapes to a pot of porridge under the eaves and people heading home. The clay jar stays in hand the whole time and the characters walk slowly, so the act of bringing a gift home is easy to see; the family walks along the courtyard wall toward the gate and the elders come out to greet them, and the gift and the reunion give this custom a concrete form.
04
From Plowing Preparations to the Vitality of a New Year
The farming shots focus on wheat seedlings turning green again and preparations for plowing, and crawler tractors in the fields carry more energy than talking about spring plowing in the abstract. The ending moves through a bamboo-forest village in rain and mist, wheat fields under sprinklers and a high-speed train crossing a sea of bamboo, linking nature stirring to life with a pace of life that keeps moving forward.

The Finished Rain Water Episode
We completed a vertical Rain Water short of about 48 seconds, with the institution's logo, narration and captions, released on WeChat Channels.
Case Study
Liandan AI Studio × NDRC | Rain Water Falls on the Second Day of the New Year: 48 Seconds From a Lantern to a Family Visit
In 2026, the Rain Water solar term fell on the second day of the first lunar month.
On one side, New Year; on the other, a solar term. On one side, spring rain across the land; on the other, a family visiting the wife's parents.
This is the Rain Water episode of the 24 Solar Terms vertical short series we made.
In 48 seconds, it had to hold solar-term knowledge, spring plowing and New Year cheer, without feeling cluttered.

When a Solar Term Meets Spring Festival, the Opening Shows “It's New Year”
Every episode in the series has a fixed structure: it opens with “Good morning, today is…” announcing the date, then covers the solar term, its seasonal signs and customs, and ends with good wishes for daily life; it uses third-person narration throughout, with no dialogue between characters.
The Rain Water episode had one more condition: it fell on the second day of the first lunar month. The first line of narration is “Amid the joy of the New Year, we welcome Rain Water,” so the images had to show the New Year feeling first.
For the opening we tried apricot blossoms and small birds in the rain, then switched to a red lantern under the eaves at the Summer Palace: the camera pulls back to reveal a whole pavilion hung with lanterns; in the next shot, on West Lake, a lantern-hung boat glides through the misty rain. A touch of red against a bluish-gray rainy day makes both New Year and Rain Water clear at once.

Instead of Reciting the Three Signs, Let Animals and Plants Act Them Out
Rain Water has three seasonal signs: otters lay out fish, wild geese return, and plants begin to sprout. The series script never recites “the three signs” directly; instead it says “otters carry fish to the bank, wild geese fly from south to north, plants put out new shoots.”
We gave each sign a visible action. On a rock beside the Yarlung Tsangpo canyon, an otter puts down its fish and goes back into the water; a flock of geese flies past Xi'an's Giant Wild Goose Pagoda, whose name is a perfect echo; and the last shot is in the Wei River wetlands, where geese fly low as tender shoots rise from under the water and grow into a clump of reeds.
The new-shoot shot used three final images as first and last frames, taking the shoots from nothing to something and from small to tall, so the geese and the shoots connect in a single shot.

Spring Plowing Shots Farmers Would Recognize
The line “farmers begin clearing irrigation ditches and repairing field banks” was first drawn as polder fields south of the Yangtze. But farming shots have to ring true to people who have worked the land: where the fields are in early spring and what machines are used must match real farm work.
We researched early-spring irrigation and plowing preparations and moved the scene to the Jianghuai Plain: winter wheat greening on the left, flooded fields on the right, and several red crawler tractors turning the soil in the water; on a ridge in the foreground, one person bends to repair the bank while another carries fertilizer.
With only paddies and wheat seedlings, the image felt monotonous; placing the land and paddies side by side and lining up tractors from near to far brought out depth and a sense of order. For color, the water leans cool blue and the seedlings fresh green, keeping the crisp chill of February sunlight.
The sprinkler-watered wheat at the end is a farming shot too. With only a first frame, the spray mist never appeared; once we added a last frame showing where the mist comes from and where it lands, the lines began spraying fine mist one by one.

A Pot of Porridge and a Clay Jar Bring New Year Under the Eaves
For the customs, choices were made first in the script. Rain Water has many folk customs, and we chose two that today's viewers know and that can be shown clearly: eating more porridge during Rain Water to nourish the spleen and stomach, and bringing jars of meat on a visit to the wife's parents.
This year, the second day of the first lunar month was already the traditional day to visit the wife's parents, so the custom and the solar term coincided. On screen, porridge simmers on a small red clay stove under the eaves of an old Huizhou-style house; a family of four in new red clothes walks along the courtyard wall to the gate, the father carrying a clay jar sealed with red paper, and the grandparents come out to greet them.
To keep the clay jar in frame from start to finish, we switched which hands held the jar and the gift box and slowed the characters' walking pace, giving the act of “bringing a jar of meat” time to be seen.
The first version of the reunion shot showed the family eating around a table. With many people at the table and little movement, a few seconds weren't enough to tell it was “a visit to the wife's parents”; changing it to arriving at the courtyard gate, with the grandparents coming out to greet them, made the meaning clear in a single action.

What this project achieved
The final delivery for the Rain Water episode was a 48-second, 9:16 vertical short with narration, captions and the presenter's logo, ending on the card “Presented by the NDRC,” and released on WeChat Channels.
In February the northern landscape is still rather bare, so this episode was set mainly in the south, traveling from the Summer Palace to West Lake, the Loess Plateau, the Yarlung Tsangpo, the Wei River wetlands, the Jianghuai Plain, old houses in Wuyuan and bamboo forests in Anji, and closing with a high-speed train crossing a sea of bamboo to link the solar term with the country's development today.
For the client, it gave solar-term knowledge a visual form: the three signs are the actions of animals and plants, and the customs are things in a family's hands. For us, the key to a series is a unified structure for every episode, no repeated images, and details that hold up to scrutiny.

FAQ
FAQ
How does an AI solar-term short make sure its seasonal knowledge and farming scenes are accurate?
Every shot is researched before images are generated. For this film's farming shots, we researched early-spring irrigation and plowing preparations and set the scene on the Jianghuai Plain, showing greening winter wheat, flooded fields and crawler tractors; we also checked flowering times for the opening: apricots don't bloom in Beijing in February, so lanterns and misty rain on West Lake were used to show the New Year rain instead.
How long did one solar-term episode take from script to delivery?
The Rain Water script was refined from late January and finalized on February 3; image generation began on February 4, the first cut was ready on February 5, the opening, plowing shots and voiceover were then adjusted, and revisions were finished on February 10, more than a week ahead of the solar term on February 18.
How do you keep every episode of a series consistent?
Every episode of the 24 Solar Terms series opens with “Good morning, today is…” and orders the narration as date, solar term, seasonal signs, customs and good wishes, all in the third person with no dialogue; the presenter's logo stays in the top-left corner, every film ends on the same presenter end card, and each episode delivers a vertical video, a vertical poster and a banner.
How sharp can the images in a vertical solar-term short be?
All stills for this film were generated at 9:16 in 4K, and the finished film is 1072×1906 vertical, suited to vertical playback on phones.
Approach
From Gathering References to Fine-Tuning Key Actions
The storyboard splits the narration into segments: the New Year setting, the three signs of Rain Water, farm work and family life. In pre-production we gathered references from books and on customs, then wrote the composition, camera movement and action for each shot; wide nature shots alternate with close family scenes, so viewers can learn about the solar term step by step as they follow the images.
Every image was first checked against the time and place the solar term belongs to: the opening uses lanterns to show New Year, and the farm work is set on the Jianghuai Plain in early spring. In the homecoming segment, the characters walk more slowly and the clay jar stays in hand, followed by the walk to the gate, giving the key customary actions enough time to be seen.
