Lung Kong Tin Yee Association

Since then, the Lung Kong associations have grown and spread over the world, fueled by the Chinese diaspora, with total membership in the millions.

[2] The Lung Kong Ancient Temple was founded 1662 by members of the four clans -- Liu (劉), Guan (關), Zhang (張), Zhao (趙) -- in the village of Lung Kong (Longgang), Shuikou district in Kaiping (開 平), Guangdong (廣 東), to foster the moral community and unity of the Four Families (四 姓 一 家).

The solidarity of the four clans can be traced all the way back to the sworn brotherhood in the late Han dynasty of the Four Brothers: Liu Bei 劉 備 (161–223), Guan Yu 關 羽 (160–220), Zhang Fei 張 飛 (?–221), and Zhao Yun 趙 雲 (?–229).

In 184, Lui Bei, Guan Yu, Zhang Fei, took the following legendary oath of brotherhood at the Peach Garden; in 200, Zhao Yun joined them to form the Four Brothers.

In 1876, the four families of (in Cantonese) Lew (劉), Quan (關), Jung (張), and Chew (趙) built a "Lung Kong Ancient Temple" in the heart of San Francisco Chinatown, a replica of the same Temple in Shui Kou district (水口镇) of Hoiping (開平) built in 1662 as a place of worship and meetings.
