It seems to be episode 16-Lele went on a hunger strike. During this period, Lele developed a bad habit of being picky about food. He said that the bread his mother bought for him was out of date, and he threw it in the trash can without accepting his father's criticism. His parents were very angry and decided to educate Lele in a special way. Lele decided to earn money to buy food, but Lele didn't make any money outside for several days. Hungry, he came to Happy Planet for help. A few friends thought hard and finally gave Lele a bad idea, asking Lele to do homework for her classmates in exchange for a certain reward. But when Lele handed his homework to his classmates, they told him that he could not pay until the teacher changed, which forced Lele to continue to starve. It's lunch time again, and Lele, who is tired and hungry, meets an old man who sells steamed buns. Lele kindly helped grandpa sell it in the market. When a basket of steamed buns was almost sold out, grandpa gave Lele some steamed buns to express his gratitude, and Lele accepted them happily. At this time, Lele felt that it was not easy to eat by his own labor and realized his mistakes.
