Tong wars of old Chinatown

A history of crime in early SAN FRANCISCO wouldn't be complete without examining the TONG WARS.
HERBERT ASBURY addresses the secret-society Chinese gangs, the tongs, in his 1933 classic, "THE BARBARY COAST."
Asbury writes:
"The most spectacular and at the same time the most powerful agencies in the underworld of Chinatown were the tongs, which were always deeply involved in every evil scheme concocted in the quarter."
The tongs operated much like Sicilian Mafia organizations in other big cities.
Asbury writes:
"Each of these organizations employed professional murderers and also recruited a force of boo how doy, or fighting men, among its own members. In later years, the tong warrior fought with revolvers, bombs and even machine guns, but in earlier times his favorite weapons were hatchets, daggers, knives, and bludgeons, which he carried in a long silken belt wrapped around his body beneath a loose blouse."
As I am reading about the tongs and the early days of San Francisco's CHINATOWN, I can't help but think:
The Chinatown of opium dens and gambling halls is now the Chinatown of cheap trinkets and tourists mistakenly wearing shorts because they think all of California is warm.
That makes me a little sad.
