Chinese style: you can marinate some quail eggs and chicken wings, or you can get some Guandong cooking or something;
Western-style: Cookies and cupcakes can be made, and cakes and pizzas can be made with good skills (cakes with pictures are all DIY by parents);
parents can also make some local snacks, such as dough twists, hemp balls, taro balls, and rice cakes. In short, don't cook too much soup or food that is not easy to eat.
