I just came back from Changbai Mountain. It's great. You'll feel it when you go. About five days from Shijiazhuang to Changbai Mountain, to Yanji to Tumen River, to Erdaobai River, to Tianchi! All the itineraries are planned! One person went alone, traveled poorly, did not buy souvenirs, came back to make a special plane. It took more than a thousand to make one trip. Newspapers are all around 3000. They can also play. They are worth it. It's a little bit of an idea to settle down.
