There is a calligraphy by Fan Xiao at home with Hangyi's signature on it. I don't know either of them, please ask an expert to introduce them.

It's Yihang, not Yihang. Fan Xiao and Yihang are the same person (real name and stage name). Baidu searched, as follows:

Shen, the stage name yihang. Born in 194 1, Suqian, Jiangsu. In 2005-06, the Ministry of Culture, China Modern Artists Association and other units organized exhibitions and cultural exchange activities in ten countries in Japan and Europe. Yangzi Evening News, Fashion Consumption Magazine, etc.

The last seal is: people live long.

The seal of the inquiry is: Zhou, and the seal of our gang is unclear. If the seal of Zhou and Bengang is stamped from top to bottom, then the author is Zhou Bengang. Baidu can find it at once.
