So how did this piece of China come about? In 1949, as Mao Zedong and his communist armies marched southwards towards Kunming, two Kuomintang armies were trapped with their backs to the Burmese border. In a series of bloody battles, they fought first the Burmese army and then the Chinese Communists to a standstill and retreated into the mountains of Thailand under a ceasefire agreed to by the Burmese. In 1953, a multi-national committee supervised the return of 7288 Kuomintang soldiers to Taiwan. Nui, who is in his early 60s, remembers the evacuation.
"We ran down in our bare feet to Chiang Rai's airfield. There were planes taking off every minute and clouds, clouds of dust."
That same year, the King of Thailand gave Mae Salong to the Chinese soldiers who had decided to stay. These last remnants of the two armies settled down and repaid the favour when they served in squads of 200 and joined the Thai government's war against the Miao Communists in the Khao Ya mountains.
Today, Mae Salong is a peaceful place. Its temple boasts an excellent museum and a moving memorial hall dedicated to the Kuomintang veterans who died in this remote place.
Mae Salong can be reached by a two-hour drive along steep and winding mountain roads from Chiang Rai.
A day's guided tour from Chiang Rai will cost about $35. And that famous Chinese noodle lunch sets you back a mere $2.
