His name is also romanized as: Chun Chun Yee / Chan Yin Yee.
Shifu Chen Zhen Yi began his studies under shifu Luo Guang Yu in Shanghai at the Jing Wu school. Shifu Chen Zhen Yi graduated under shifu Luo Guang Yu in Shanghai and became his room-mate for many years.
Shifu Chen Zhen Yi moved to the south with shifu Luo Guang Yu and helped him set up his Kowloon school. Shifu Chen Zhen Yi was actually the first person to teach such people as shifu Huang Han Xun (Wong Hon Fun) and shifu Zhao Zhi Ming (Chiu Chi Man). This makes shifu Chen Zhen Yi the senior brother to all of shifu Luo Guang Yu’s students from the south and places shifu Chen Zhen Yi as a Luo Guang Yu’s senior disciple.
Shifu Chen Zhen Yi set up a small class in Kowloon and taught Seven Stars Praying Mantis in an old-fashioned way. He was frequented by shifu Luo Guang Yu, until shifu Luo moved back to Shangdong.
Students from shifu Chen Zhen Yi’s lineage still practice sets that were not taught to later students of shifu Luo Guang Yu, for example a Spring and Autumn Guan Dao form not known to other branches of Seven Stars (different from the Da Kwan Dao set).
There is little difference between shifu Chen Zhen Yi’s students and shifu Huang Han Xun’s in the way of forms. For example, forms like Beng Bu, Shi Ba Sou, Cha Chui, Bai Yuan Tou Tao, and others appear to be nearly identical except for the pacing of the forms. Shifu Huang Han Xun’s forms phase each movement very distinctly in each expression of Jing where it seems that shifu Chen Zhen Yi’s students do not space them quite as far apart.
