Lugu Lake
Kublai Khan, with his Mongolian army, established his army headquarters south of Lugu Lake. A feudal government ensued when officers and troops were stationed here. Kublai Khan introduced Buddhism and enforced rules of civil administration, coupled with religious tenets around Lugu Lake and Yongning. It was during this time that the practice of monogamous marriage practised by officials of Mongol army also came into vogue among the ethnic Mosuo people, particularly in the Yankouba and Tuodian villages.
