Who is the real person of Yunnan Insect Valley Horse?

Yunnan Worm Valley Horse is a Taoist expert introduced by Chen, a blind man who is good at divination and geomantic omen. The typical feature of Ma Zhenren is boasting that his ancestors were all masters of Feng Shui for eight generations, and he was proficient in learning gossip. For Zhang Yingchuan who questioned him, Ma Zhenren gave prevarication and ridicule.

At the end of "Yunnan Worm Valley", Wang Pangzi and Chen found the blind man and asked him about Yin and Yang Feng Shui. After eating wonton, Blind Chen told them that they could ask Ma Zhenren to answer their questions.

Blind Chen and real Ma are a group. Chen, a blind man, tells fortune, while Ma, a real man, looks at Feng Shui. They all admire each other and collude with each other. The ultimate goal is nothing more than eating and drinking. Zhang Yingchuan also appeared with Ma Zhenren. In order to highlight Zhang Yingchuan's true skill, Ma Zhenren became a supporter.

Ma Zhenren told the villagers about building a school, and Zhang Yingchuan retorted. Ma Zhenren also said that after the geomantic omen in this area, he can be the top scholar. Zhang Yingchuan said that there are so many termites here that it is impossible to build a house. The two men argued for a while, and finally Hu Bayi decided to go to Zhang Yingchuan instead of Ma Zhenren. In this way, Zhang Yingchuan won the trust of Hu Bayi.
