Where do two birds compete for a good day in spring?

Han Zhuan is a history book written by Ban Gu. In the past, the system of the former king was different from that of emperors, officials, Hou, Qing, doctors and scholars, and those who engaged in smuggling, holding customs and beating (tuò) were not allowed to be arrogant. The husband is natural, so he decides the people from top to bottom.

Cultivate in time, but use it sparingly. The vegetation has not fallen, and the axe is not in the mountains; Wolves and otters don't sacrifice, and the net of auspicious rigidity is not distributed in wild ze; If the falcon didn't attack, it wouldn't be used in the tunnel.

Take things in time, but if you don't stubble, you won't cut them. yuán, Mi eggs, salty, are often forbidden. Therefore, it is so well-prepared, timely release of gas, rich in things, sufficient functional reserves. Then, four people, because of their local conditions and their intelligence, stayed up all night. In order to run their industry, they got along easily and they all supported each other. Unless there is a job fair, they are salty.
