 East of Hanyuan, the Dadu enters the Dadu River Canyon () before reaching the lowlands of the Sichuan Basin just below Mount Emei.The Dadu River receives the Qingyu River tributary and meets the Min at Leshan.At the confluence of the Dadu with the Min, the Dadu possesses both greater water volume flow and a further source so it is considered the true course of the Min River system.
