"You can't eat it." Zhang Han thought for a while, and said to Mengmeng very seriously: "Mengmeng, you can only eat the food cooked by your father. If you want to eat something outside in the future, you must first tell your father. Some things are poisonous. It will...be ugly if you eat it, you know?"

Among the spiritual treasures of medicinal herbs, there are usually some highly poisonous things. If you plant some on the Crescent Mountain in the future and Mengmeng accidentally eats them, let alone whether they can detoxify, it will make Mengmeng feel uncomfortable. Han wants to see.

Therefore, some things need to be taught step by step in advance. Children's cognition of the world is still in the growth stage, and they don't understand many things, so they need to be taught step by step.
