Zhang Qixuan, a young boy studying in the United States in the late Qing Dynasty who was born in 1871, became "close friends in the mirror" with Jesse Livermore on Wall Street. By integrating Eastern philosophy (Tao) with financial practice (skills), he practiced the "system-invincible" longevity method, and formed a "one inside and one outside" brotherly cooperation with his brother Zhang Qiming to protect the family and pass on wisdom in the turbulent century.
