When does the Mekong River flow to the southeast?

1 1 month to the following April winter.

Tonle Sap Lake, the largest freshwater lake in Southeast Asia, is the food and clothing parents who gave birth to Cambodians. Whenever spring comes to the earth, the meltwater from the Qinghai-Tibet Plateau in China flows into the Mekong River. After arriving in Phnom Penh, the amount of water was so great that Tonle Sap Lake, which was originally in the southeast, changed its direction, flowing to the northwest and flowing upward into Tonle Sap Lake. Coupled with the abundant rainfall brought by the Indian monsoon in May 5- 10/October, Tonle Sap Lake gradually grew into a large lake with an area of over 1 10,000 square kilometers. From 1 1 month to April of the following year, the water in Tonle Sap Lake flows down the Tonle Sap River. At this time, the direction of water flow turns to the southeast. After Phnom Penh meets the Mekong River, it continues to the southeast and flows into the sea through Vietnam. In other words, in the dry season, the area of Tonle Sap Lake will be reduced to more than 3,000 square kilometers. In rainy season, the dock is only 9 kilometers away from the urban area; In the dry season, the distance becomes 17 km, so the residents here have to migrate frequently with the change of seasons. Houses and boats living on both sides of the lake follow the way that the old ancestors get along with nature, live in traditional high-rise houses or fishing boats on the water, work at sunrise and rest at sunset, and blend in with nature.
