Why were the ancients called Songhua River?

Because in ancient times, there were dense vegetation on both sides of Songhua River, and there were many pine trees. The male of pine trees had pine flowers (also called pine yellow), which often rushed into the river after heavy rain. There are many pine flowers floating on the river, hence the name Songhua River. There is also a saying that it is named after the flower string (pine flower) formed by the rime spectacle on the riverside in winter.

Rename: From the Eastern Jin Dynasty to the Southern and Northern Dynasties, the upstream was called fast water and the downstream was called difficult water. During the Sui and Tang Dynasties, the upstream was called Xiaomi Shuishui, and the downstream was called Nahe. In Liao Dynasty, it was called Huntong River, but now Fuyu section is called Yahe River. During the Jin Dynasty, the upper reaches were called Songwa River and the lower reaches were called Huntongjiang River. In the Yuan Dynasty, the upper and lower reaches were collectively called Songwa River. Songhua River (homophonic Songwa River) was first named in Xuande period of Ming Dynasty.
