The Golden Triangle is a triangle in the border areas of Thailand, Myanmar and Laos in Southeast Asia. You can often hear the term on TV. The Mekong River is another important geographic reason for the formation of the Golden Triangle. It flows southward from Qinghai in Northwest China, through six countries: China, Laos, Myanmar, Thailand, Vietnam and Cambodia. We booked a day's Tour online in advance, arrived in the Golden Triangle in the afternoon, and went to Laos by boat after a short stay. Listening to the names, we felt hesitant. We watched a lot of Ha-ha TV dramas.
