In 2010, a joint archaeological survey team organized by the scholars from China, the United States and Canada conducted archaeological survey in the southern and western parts of the Lake Dian Basin. The surveyed areas involved three towns, which were Kunyang in Jinning County and Haikou and Biji in Xishan District, Kunming City, covering areas of about 74sq km. The survey methods included onsite survey, core observation and hand coring test. The survey discovered two microlithic sites, 21 sites of the Bronze Age, five sites containing remains of both the Bronze Age and the Han Dynasty and one site of the Han Dynasty.
