Introduction: Le Taotao is a naughty little guy. He is nine years old and is in the sixth grade of Mengmeng Primary School. He is a smart kid. No, rather than being smart, he is a genius. Yes, he is a little genius. He was supposed to be in third grade, but he jumped directly to sixth grade. In fact, the fact is that he has already graduated from graduate school, but his family wants him to recall his childhood life and requires him to go to elementary school. Anyway, he has plenty of time. In the end, because his grades were so good, the teacher had nothing to teach him, so he had to be promoted directly to sixth grade. However, he is the smallest and cutest among the sixth graders. Lively and naughty, he often does things that make people laugh or cry. At the same time, he brings a lot of joy and laughter to these big brothers and sisters, and also makes this tense and dull class full of life. Therefore, our little Tao Tao is still very popular~~~~~ So everyone gave him a nickname - "Little Naughty Pistachio", because wherever he is, there is joy and laughter. And our little Taotao is very satisfied with this kind of life now. However. . . . . . . . A birthday party changed everything for him. . . . . . . . .
