Ning Guan went on reading as before.

You are not my friend.

There are two things: first, when they are hoeing vegetables in the garden, they see that there is money in the field; second, when they go through the etiquette ceremony outside the school gate, they do something different, which shows their personality level. Ning Guan and Hua Xin were picking vegetables in the garden when they saw a small piece of gold on the ground. Guan Ning kept hoeing, just like seeing stones and tiles. Huaxin picked up the gold coin and threw it away. They used to study at the same table, and an official passed by the door in a high car surrounded by obstacles. Guan Ning continued to read, and Huaxin put down the book and went out to read. Ning Guan cut open the mat and sat down separately, saying, "You are not my friend."

Stick to principles and make friends carefully.
