How to write the theme of Hua Bobo's picture book?

Uncle Hua is a traditional food, but it is not ordinary pasta. Flower cakes with different shapes and patterns have far-reaching implications, expressing people's yearning for a better life. The raw materials of the flower cake come from the vast land, which is very grounded and endless. In spring, seeds are sown. In the following days, wheat always grows proudly, turns green, gets up, jointing, raises the flag, germinates, heads and blooms ... After careful care of the cultivators, it's time to harvest, and full wheat grains are covered with fields. Making flower cakes is not a simple matter, it requires many processes, and the process is long and full of fireworks. First, grind new wheat into flour, then add eggs, sugar, peanut oil and water to the flour and start stirring. You can't be lazy in the next step, because only by spending enough time and energy can you knead the gluten dough. After finishing the above basic work, you should use a hundred times of patience and creativity to knead dough flowers, otherwise, you will only get pieces of big, white and round steamed bread. Small dough, after being rubbed with dexterous hands, turns into lifelike lotus, peony, chrysanthemum, peacock, mandarin duck and lion.
