How do you know blind Chen?

In the novel "The Wrath of Ghost Blowing Lights: Clear Xiangxi", Hu Bayi confessed in his memory that he met the blind Chen Man in Beijing. At that time, the blind Chen Man was a famous fortune teller. At the request of Professor Chen, a salvage team was formed to salvage Zhao, a national treasure in the coral spiral shipwreck. After getting the ancient mirror, they got the clue that there was Inner Dan in an ancient tomb in Hunan, which was suspected to have been lost.

It is not easy to find the whereabouts of blind Chen in Beijing, because his whereabouts are erratic. Later, he and his family learned about the whereabouts of the blind Chen among the people familiar with Panjiayuan.

The blind man is Chen. When I was young, I entered the ancient tomb of Pingshan in Xiangxi with the partridge whistle.

Partridge whistle is Yang Ping's grandfather. Chen, a blind man, told the story of his experience and ending in Pingshan, Xiangxi, and gave them the latest clues. So instead of going to Pingshan, Xiangxi, he found Professor Chen with new clues to study again.
