You can go to Baidu to check the specific location on the map. Follow-up: I said that Heilongjiang is not the answer to Xinjiang: coat, friend, sorry, wrong. Please forgive me. Follow-up: Do you know? Answer: Sorry, I don't know about Heilongjiang, but you can refer to some archaeological documents, where there should be some recorded information. I looked it up for you. Please refer to the following information: there are 26 sites of prehistoric jade unearthed in Heilongjiang Province, which are distributed in the vast areas outside the northern Daxing 'anling and Xiaoxing 'anling Mountains. Most of these sites are located on platforms or hillsides on both sides of the river, which can be roughly divided into three areas from west to east. The western region is located on the banks of Nenjiang River, Wuyuer River and other rivers, including Tazi City in Tailai County, Wenggen Mountain in the east and Qi Teng City.

I really don't know, but according to archaeological findings, there should be a place that produces jade near this place, because imagine that the ancients could not say that they would dig jade all the way and then go back to their tribe to make jade? There should be jade-producing places near their tribe for reference only. Since there is gossip, you have to consult the published experts and friends. I wish you success!
