Later, many people also wrote "mottos" along with them. For example, Du Fu, a famous poet in the Tang Dynasty, wrote such a poem in order to urge himself to correct his addiction to alcohol: "Put up with what is in the cup and just read the motto."
Motto can sometimes be used to warn others. For example, in the Northern and Southern Dynasties, there was a monk who saw that all monks in the temple were lazy and afraid of suffering, so he wrote a motto to encourage them: "Diligence can make up for the shortcomings." It means that the harder you work, the harder you work, and the time to understand the truth is not far away.
In the first year of Qing Daoguang, Chen got Yue Fei's inkstone in Beijing. The inkstone is purple, square and long, and the back is engraved with the words "leave blank, not phosphorus and not slippery", which is a running script. After this inkstone was acquired by Wen Tianxiang, Wen Tianxiang also engraved an inscription: "Although the inkstone is not hard to grind, although the heart is not like a stone, you should not get lost and ask for many blessings." Yue Fei and Wen Tianxiang took this inscription as their own life rules.
Mottos are often written as banners to be hung in study rooms and places where people often rest, such as the word "control anger" written by Lin Zexu.
