Chinese in northern Thailand
The KMT soldiers came from Yunnan Province in China. So they speak mainly in Yunnanese, a dialect that is very different from Mandarin. The children go to both Thai and also Chinese school as well to learn Mandarin. Many are trilingual, as they speak Yunnanese at home. Some of the wealthier ones go to continue their study in universities in Taiwan. Most households have satelite tv channels from China, Taiwan and Hong Kong, with at least 10 Chinese channels. All the Chinese households have the traditional good luck writings on or around the door. The inside is quite traditional as well.
If you can speak Mandarin, it can be a very interesting trip as you can always hear stories about life in the tough days from older folks.
