In the Ming Cult and to wulin in general, Tse Tsun was known by the nickname "Golden-Haired Lion King." Indeed, during the story of HSDS, Tse Tsun had a mane of "golden" colored hair that gave him a leonine appearance.
Did Tse Tsun always look like that during his adult life? He already had his famous nickname during the time before his family was murdered by Sing Kwun, but at least in HSDS '86, he originally had natural and common (for East Asian men) black colored hair, and only gained his "golden" hair after training in the Hung Dung Sect's 7 Seung Fist.
If Tse Tsun didn't always have golden hair, what caused his hair to change color? Was it due to learning 7 Seung Fist (why would that change his hair color anyway)? Also, why did he have the nickname "Golden-Haired Lion King" as a young man if he didn't have golden hair yet at that point?
