TS why you put the Thais in your list? Thais are ok people... I made few Thai friends from my recce adventures at Beach Rd and Golden Mile.. They maybe rowdy when drunk but generally they are better than those fucktard Pinoys and Ah Nehs and loud crude Ah Tiongs.. I voted for India Ah nehs to be booted out but if given the choice I would vote Pinoys, Ah Nehs and Ah Tiongs to be kicked out of this place..
In temperament, Pinoys are actually easy-going, friendly people just like the Thais.
However, Pinoys have the tendency of being more 'flamboyant' or 'showy', more gossipy and more clannish than the Thais. You can see how this potentially becomes a problem when Pinoys become middle managers. Maybe this is a legacy of the Philippines having been colonized by Spain and America.
Thais are more 'fatalistic' (let whatever happen, happen lah, cannot fight fate), no doubt influenced by Buddhism.
China is a big place, and there are many classes of Ah Tiongs. You'll find that the folks from Shanghai are more materialistic, because that city has penty of
nouveau riche. Sichuan folks are more down-to-earth and humorous, but may become grouchy or sarcastic. Beijing/Tianjin/Northeasterners are a tad more elitist, especially when they deal with southern Chinese. The hinterlanders (Hebei/Henan/Hubei/Hunan/Anhui etc) are a mixed bag of provincial folks. Many older hinterlanders still remember the Cultural Revolution when they suffered greatly, therefore they want to get rich quick at any cost.
