I want to know the answer to the following question:
Which river does the province of Zhejiang derive its name from?
All the background I'm provided with is that "The province's name derives from the Zhe River (浙江, Zhè Jiāng), the former name of the Qiantang River which flows past Hangzhou and whose mouth forms Hangzhou Bay.". Is that enough to answer the question?
Answer: yes
