How should I sign at the end of the year when writing calligraphy? It can be written as "Xin Mao Sui Sui Xian Shu" in this way.

Yes

Xinmao Jidong and so-and-so can be clumsy

A year is divided into four quarters, one quarter has three months, and each month accounts for the three characters Meng Zhongji. Each quarter occupies the four characters of spring, summer, autumn and winter, so that these twelve months can be named. Taking October, November and December as examples, they are Mengdong, Midwinter and Jidong

Of course, other times, such as Xinmao Mid-Autumn Festival XX Written in Shanghai, so and so in the early spring of Xin Mao

On August 22, Xin Mao, XX was written in XX, etc.
