01 / Background
How do you let viewers sense a turn of the seasons on screen?
The End of Heat episode is about summer heat fading and the harvest drawing near. No single object can explain this shift in the weather, so the film uses lake water, hostas and morning mist in the mountains to bring in a sense of coolness, then shows the anticipation of autumn through ripening fields and a family meal.
Nature, produce and family scenes tell this solar term together: viewers first feel the season changing, then see how that change shows up in the fields and in daily life. The short moves steadily from the landscape to the people.
02 / Creative Highlights
Letting coolness and harvest unfold through color.
01
Color that tracks the turn of the season
The blue-greens of lake water and mountain mist gradually give way to the warm gold of rice fields and food. The shift from cool to warm mirrors the heat fading and the harvest approaching, so as the image changes, the story moves forward too.
02
Everyday scenes that pick up from the landscape
Rivers, fields and fruit trees are wide, open views, while the dinner table in the courtyard pulls the eye back to somewhere familiar. Linking landscape to family gives the seasonal explainer human feeling and concrete daily life. The meal scene focuses on small gestures: the family's glances, ladling porridge, picking up food with chopsticks. These familiar actions tell viewers at once that this is a family.
03
Seasonal food as a doorway to memory
Duck, tea and the family meal turn customs into scenes you can see. The food close-ups give the short a moment to pause and connect seasonal knowledge with everyday life.
04
One landscape, two textures in the film and the poster
The short uses sunset glow and reflections on the water to convey the cool of evening, while the poster renders the same scenery as a traditional Chinese gongbi painting. The peaks, stone bridge and sky keep the same layout, so it's instantly recognizable; the calligraphy title and blank paper space match the style of the series' other posters.

06 / Results
Memories of End of Heat rest between harvest and reunion.
We completed a roughly 48-second vertical short for End of Heat, plus the official poster and banners. The short moves from lakes, mountains and animals to seasonal food, the family table and the orchard; the poster uses the stone bridge at sunset as its main image, so the video and the graphics work as a set.
Case Study
Liandan AI Studio × NDRC | End of Heat: Every Fruit in a Squirrel's Paws and Every Crop in the Field Has to Be Right
The “chu” in the Chinese name for End of Heat (Chushu) means to hide away or come to an end: this is where the summer heat should retreat.
This episode is about a turning point: the days are still hot, but mornings and evenings have turned cool, and the crops in the fields are nearly ripe.
We made the End of Heat episode for the 24 Solar Terms series: about 48 seconds, 11 shots, in 4K vertical format, from a boardwalk on a lake to a branch full of pomegranates. We also repainted one of the shots as a gongbi-style poster.

01
The fruit in the squirrel's paws has to have a name
For the shot explaining the character “chu,” we used a squirrel: it nibbles a fruit a few times, then leaps off the branch, leaving it empty. “Hiding away” and “coming to an end” are told in a single action.
But what fruit is the squirrel holding? In an explainer for a government account, everything on screen has to be nameable, not some “wild berry” of unclear variety. We made it clearly an apple and redrew the skin: red with yellow, fine streaks, and a stem on top.
First draft: a bright red fruit nobody could nameFinal: a red-and-yellow apple with a stem
Why not have the squirrel eat a pine cone? Pine cones are brown, almost the same color as the squirrel's fur and the bark. A red apple adds a spot of brightness to a frame full of green and brown, and squirrels eating apples is common in real life too.
02
Late August fields need crops
For the line “the nights begin to feel a little cool,” we used a stone arch bridge beneath karst peaks at dusk: the sky glows pink and orange, and the bridge and its reflection form a circle on the water.
The first draft had two details that didn't match the season or the terrain: beside the bridge were freshly flooded empty paddies, though by End of Heat the fields should be full of crops; and the water under the bridge was blocked by field ridges, looking like separate ponds rather than one continuous river. The final version replaced the area behind the bridge with a nearly ripe rice field and rearranged the water so it flows under the bridge like a river.
The next line, “crops planted in spring begin to ripen,” followed the same thinking. The first draft was a close-up of a single sorghum plant, showing just one stalk; the final version became an aerial view of vast rice fields with a river curving through the gold, because ripening happens across a whole stretch of land.

This episode's dinner table doesn't look like the last one's
Almost every episode of the solar terms series has a family meal scene. By the fourteenth episode, we lined up the meal shots from earlier episodes side by side and found that the courtyards, tables and people could easily start to look alike.
For End of Heat, the courtyard became a small white-walled one with flowers planted by the door; the characters were set as a family of four, with the father ladling porridge for the children, one child smiling and the other sipping with head bowed. What's on the table also follows the narration: “foods that nourish qi and blood” became a big bowl of red date, millet and lotus seed porridge with a few light home-style dishes.

A Family of Four Sharing Porridge
Red date and millet porridge with a few side dishes, matching “foods that nourish qi and blood.”
The shot before it, “eating duck at End of Heat,” followed the same idea: a plate of braised duck, a cup of tea, a dish of dipping sauce and a pair of chopsticks, with a few yellow leaves on the table, so viewers know at a glance what is being eaten and in what season.
04
The same stone bridge, repainted as a gongbi poster
The cover poster uses this very stone bridge at sunset. We repainted the entire realistic final frame as a traditional Chinese gongbi painting: the karst peaks, stone bridge and rice fields stay in the same positions, so anyone who has seen the film recognizes it at once; the lines and colors take on a painted look, paired with a calligraphy title and the cover line “Eagles soar across the sky as the grain comes in; joyfully we watch a thousand waves of rice.”

We also made a motion version of the poster, with clouds drifting slowly and the light shifting with them, exported a GIF version, and made a 21:9 landscape banner.

This gongbi style carried forward too: for the next episode, White Dew, we made the entire short in gongbi with light color washes.
05
What this project achieved
The solar terms films show things everyone knows: a squirrel, a rice field, a family meal. Precisely because they're familiar, viewers spot anything wrong at a glance.
For End of Heat, we checked these details one by one: the fruit has a name, the fields hold the crops of the season, and the dinner table doesn't repeat earlier episodes. The gongbi style tried out on the poster also gave the later episodes of the series a fresh look.
FAQ
FAQ
How do you make sure AI-generated animals and fruit look real and believable?
First decide the name of everything in the frame, then write it into the prompt. In the first draft of End of Heat, the squirrel held a red fruit of unclear variety; we made it clearly an apple and redrew the red-and-yellow skin, the fine streaks and the stem.
How do you make the field scenes in a solar terms film match the season?
Look up the crops in season and what the fields look like for each solar term. End of Heat falls in late August, when the fields should have nearly ripe crops, so in the stone bridge shot we replaced the empty flooded paddies with rice and turned the water, which field ridges had split into ponds, into one continuous river.
Every episode of the series has a family scene. How do you keep them from looking alike?
Line up similar shots from earlier episodes side by side, then redesign the courtyard, the characters and the dishes on the table. End of Heat used a small white-walled courtyard and a family of four, with red date, millet and lotus seed porridge and light side dishes chosen to match the narration.
Beyond the short, can you make matching posters and motion posters?
Yes. For End of Heat, we repainted the stone bridge from the film as a gongbi painting for the cover poster, and also made a motion version with moving clouds and light, a GIF version and a 21:9 landscape banner, all delivered on August 21 together with the 4K vertical short.
Approach
From nature scenes to a home-cooked meal.
We first turned the script into concrete scenes, spelling out what is in each frame and how it's arranged, then gathered real-world references for composition, landforms and lighting. The color of the rice fields, the autumn hues of the dawn redwoods and the look of the pomegranates were all checked item by item; local retouching kept the original lighting and composition so that fixing one spot didn't shift the whole image. The fruit in the squirrel's paws was drawn as an instantly recognizable apple, so viewers know what it's holding.
For the family meal in the courtyard, the number of people, their ages, clothing and interactions such as picking up food and ladling porridge were all set one by one. The finished film uses a family of four around the table to tell the food customs, with every gesture serving the everyday atmosphere and the colors of the setting and clothing kept soft and harmonious.
The poster was first converted from a selected realistic frame into a gongbi painting, then placed into the series poster template. At delivery we also organized the text layers, PSD files, fonts and banner layouts, and checked that the static and motion posters matched, so the promotional materials beyond the video kept a consistent style.
