Sơn Tinh – Thủy Tinh

Sơn Tinh – Thủy Tinh (The Mountain God vs. The Lord of the Waters) is a Vietnamese myth. It explains the practice of tidal irrigation and devastating floods in Vietnam as a result of monsoon—a seasonal prevailing wind in the region of South and Southeast Asia, blowing from the southwest between May and September and bringing rain (the wet monsoon), or from the northeast between October and April (the dry monsoon).

Sơn Tinh is also one of the Four Immortals, specifically Tản Viên Sơn Thánh.
