The late Baguazhang great master Mr. Li Ziming just before his death wrote an article called � Concerning the enigma of Dong Haichuan’s life experience’s � he mentioned: � After mastering his art Dong Haichuan devoted himself in the Tai Ping Heavenly Secret Organization (Taiping Rebellion) and to accomplish his mission to infiltrate Beijing, he had to serve as castrate servant in a famous mansion, being their secret agent and awaiting an opportunity to kill the King Xianfeng, later the Taiping Rebellion was defeated and the organization was dismantled, the King Xianfeng became ill and finally died, Dong decided to stay under his cover inside the walls of the Governing city.
There are in fact different opinions about the reasons which led Dong to serve as an eunuch in Su Wang mansion. Since 1883, date of the death of Dong, there are many documents which unfortunately will not be found nowadays to confirm with certitude any version.
But we can however compare with the two major motivations which led someone to serve as eunuch servant at the time of Dong Haiquan:
a) to avoid poverty, many Chinese decided for castration,
b) to avoid from sentence of death after having committed serious crime, castration was the only issue.
In autumn 1928, Wang Laisheng wrote in “Notes on Wushu”: “Dong Haichuan after having committed a serious offence to the law, was submitted to castration. He later was enrolled as an eunuch servant…” which is the very plausible possibility as knowing Don Haiquan’s impetuosity and passion for duels.
