桑森泰，是第二个澜沧王国国王，法昂的王子。中国《明史》称其为刀线歹:

他统治从1372年至1417年，名称桑森泰的起源被认为是他统治时期区域内发生政治和社会动荡的反映。桑森泰字面意思是三十万泰人，从而体现在他的统治进行了人口普查的结果。目前还不清楚人口普查是否包括整个人口或只是能够携带武器的男人。

他43年的统治期间，澜沧王国无兵战。

桑森泰有五个女儿:公主KEO Koumari，公主Anousa，公主MANORA，公主Souphutta和公主湿婆屋嘉，有三个王子是大城王国公主所生:兰亨登、Sai、Khamtèm，他的其他王子Kongkèo、Lu Xay、Fa Kheun '则是由兰纳的诺伊安沙公主所出。

Samsenethai (also called Oun Huan) was the second king of Lan Xang, the son of Fa Ngum, whom he succeeded.

He ruled from 1372 until 1417. The origin of the name Samsenethai is thought to be a reflection of the political and social upheaval occurring within the area at the time of his rule. Samsenethai literally means "300,000 Thai," thus reflected the result of a census conducted in his reign. It is unclear whether the census included the entire population or just men capable of bearing arms.
