Liu Mei prepared a nutritionist's test paper and announced a series of innovative experiments on nutritious meals after returning home. He hoped that his family would cooperate in tasting and record their true feelings as the basis of the paper. In the first stage, the food at home was very diverse and was cheered by everyone. And Dai are also coming. Next, Liu Mei began to formulate a unique nutritional formula according to his personal situation. As a result, some people are happy and others are sad, and there are different opinions. In the third round, Liu Mei tried to change people's moods and habits through diet, but it all went wrong. Liu Mei's experiment ended in failure. Surprisingly, Liu Mei's thesis was rated as the first because of its novel topic, and she was qualified as a nutritionist.
