Yesterday, my daughter specifically wanted to eat water spinach, and I found it strange that she knew water spinach, even though her fingers were not touched by spring water. I asked her,"Niuniu, have you eaten it in school?" (In fact, I have long wondered in my heart. The price of this water spinach is relatively expensive. Will the school make it for them?), The answer really was no. When I asked again, it turned out that she didn't know what a water spinach was. Sigh, after a long time, she was just fooled!
