A straw can hold a bucket of rice, and a stick is exactly one foot long. This is because in ancient times, many people went to court because of insufficient weight. In this case, the official's signature and management are the standard measuring tools.
Let's continue to play the board. Because the color of the signature is different, the severity of the play is different. Therefore, officials should not only learn the ability to recognize signatures, but also be able to distinguish the severity of the host's tone, so as to correctly understand the orders of administrative leaders.
