Tǎhé

The Ta River rises on the northern slopes of the Yilehuli Mountains and winds northeast through the forests of the Greater Khingan. It joins the Huma, which carries its waters to the Amur. This mountain country is cut by many streams, with long wooded valleys between the rounded ridges. The watershed separates rivers flowing north toward the Amur from those descending south toward the Nen, making the Ta part of the northern side of the range.
