Zhang Yingchuan is not simple, and has a deep relationship with Hu Bayi. It turns out that Zhang Yingchuan's great-grandfather was Zhang, and Zhang's apprentice was Sun, who passed on the sixteen-character geomantic occult technique to Sun, and then Sun accepted his apprentice, that is, his great-grandfather. So strictly speaking, Zhang Yingchuan and Hu Bayi were students.
Zhang Yingchuan's appearance is not so high-profile. Zhang Yingchuan was squatting on the hillside in a suit of migrant workers' clothes. Hu Bayi and Zhang Yingchuan met by accident. Under the guidance of Chen Man, a blind man, Hu Bayi came to Baiyun Mountain to look for Mr. Feng Shui, but the real Mr. Feng Shui was not found by Hu Bayi. Hu Bayi met Zhang Yingchuan when he was unprepared.
