新加坡開閩王氏總會成立於1875年，以春秋時的太子晉為王氏受姓始祖。
Singapore Min Nan Ong Clan Association (direct translate from Chinese) was set up in the year 1875, acknowledged Prince Jing of Chun Qiu Period (BC770-BC476) as their Ancestor for the surname Wang (hokkien: Ong).
太子晉，字子喬，繫周靈王太子。靈王二十二年（公元前550）冬，谷洛二水泛濫，靈王欲壅之，太子晉以民生為重，直諫阻塞之不當，被廢為庶人。傳子宗敬，徙居太原。時人稱為“王家”，因以為姓。此即太原王姓一繫之由來。
BC550, Prince Jing (name Zi Qiao) was being punished by removing his Prince title and became a normal citizen. After the title being removed, he moved to Tai Yuan district. Due to Prince Jing was a member of the Royal family, the people at Tai Yuan address his family as Wang Jia (Members from Royal), from then, the surname starts to circulate.
太子晉的第四十九代孫王審知，繫五代時閩國的建立者，公元909~925年在位。王審知，字通信，光州（今河南固始）人。唐末，從其兄王潮、王審邽起兵，入據福建。王潮死後，他繼任威武軍節度使，盡有今福建之地。後梁開平三年（909）封為閩王。閩王的後裔分散各地，其中的一支經廣州潮州、海南島，遷徙到新加坡。
In Tang Dynasty, the 49th Generation descendant of Prince Jing, named Wang Shen Zhi was given the title as Min Wang (Duke of Min Nan), from then, the descendants of Wang Shen Zhi started to scatter all over the Min Nan area (including Chao Zhou, Hai Nan, Guang Zhou, etc) and later to Singapore.
1872年，新加坡開閩王氏族人，福建同安縣白礁鄉王友海，與同裡王求和、王宗周三人，出巨資在新加坡武吉智馬律附近購買了一塊三百多畝的土地，這就是有名“姓王山”。後來他們又在姓王山修建起“閩王祠”。
1872, the later descendants of Prince Jing, named Ong Yew Hai, Ong Kiew Ho and Ong Zong Dong came out with a large sum of contribution to buy a plot of land in Bukit Timah Rd (300 over hect), this was where the folks called “Xing Wang Shan” – Hill of the Ong’s, and later part, a temple was being built at the land, given name as “Min Wang Ci” – Hall of Duke of Min Nan.
從此，新加坡王姓移民纔有了永遠的立足之地與精神歸宿。
From them the Ong Clan in Singapore has certain recognition and the spirit of staying in Singapore.
