What does the picture book Grandpa's Garden convey to children?

Grandpa's favorite thing is to take care of his own vegetable garden every day. This vegetable garden is a magical vegetable garden. This is a vegetable kindergarten. When grandpa is away, the vegetable dolls are jumping and laughing. What will happen to the vegetable dolls when grandpa walks into the vegetable garden? This is to let children observe things, arouse their enthusiasm, improve their observation ability and increase their attention. After reading it with my children for the first time, I carefully read the guide sandwiched in the book. It turns out that this is not a simple book about interesting nature, but it deeply inspires us to imagine how many unknown secret worlds are hidden in the real life around us.
