From my research, Sg Secret Societies starts with Ghee Hin as
the 1st gang in Sg.
Gradually comes other gangs.
Ghee Hin are started by the Cantonese but as days goes by, they
recruit other dialects grp as well...
Gradually, there are Ghee Hin but many sub-division according to
dialects grp...
Ghee Hin Teochew, Ghee Hin Hokkien, Ghee Hin Cantonese etc...
After the death of their big boss, Ghee Hin becomes separated in
that many ppl break away and form their own gangs too... Ghee Hock,
Sin Ghee Hin etc...
The Ghee Hin split in 1925. The 18, 108 and 08 became by products
of the Ghee Hin.
The Hokkien gangs comprises of the following groups - 08, 24, 18,
108 and 36.
Though there are a number of Cantonese and Malays in the 24 Group
also, majority consist of Hokkiens.
For the Teochews, the traditional Hok Tio Kheng was the ruling
society, commonly known as Sar Ji (meaning - Three
Characters/words). The Sin Tong Hwa is a smaller Teochew gang as to
the Sar Ji.
Among the Cantonese, the most notable were the Khwan Yi, San Wui
Khwan and the Heng Alliance though there were not as well organised
as the Teochews and Hokkien gangs.
Untill 1965, the police did not have information or know the
existence of the 21 gang. It was only during the racial riots that
the 21 Gang was exposed in their efforts to raise support for their
Anti-Malay movement.
One notable traits of the 21 Gang is its strict discipline and
members strictly follows the traditional customs and codes of the
old secret societies.
Nowadays, Gangs can also be differentiated into types or races of
the gangs.
Pek (White), Ki Kak, Siao (Mad), Chao (Smelly).
The 21 Group and some independants are the Pek type.
The 24, 108 & 08 are the Ki Kak type.
The 18 are the Siao type.
The 369 are the Chao type.
