Where is the huang river?

Hi, do you mean Yellow River? If so, it is hard to say its location. It starts to flow from Bayan Carat Mountain of Qinghai Province. As the second longest river, Yellow River flows through nine provinces of China: Sichuan, Gansu, Ningxia, Inner Mongolia, Shanxi, Shaanxi, Henan ans Shandong. Its whole flowing route forms a "几" in Chinese.
