Who will entertain you when you go to the barbecue city alone? Four women don't entertain them because they earn money to buy drinks. How many drinks can you have by yourself? Hehe, so the more famous the place, the less you can go.
Get off at Yanji Railway Station, take a taxi and tell the driver to go to Yanda. Why did you go to Yanda? Visiting friends? There is no other reason to go there. After you finish your work in Yanda University, you can take a taxi to the West Market. With a mouth under your nose, you can find a place to sell specialty products by asking casually. There are many specialties here, but don't buy any ginseng antler. You can't tell the truth from the false, and people won't eat it or use it if you take it back. Just buy some snacks. You can buy dog broth in vacuum bags and make it locally in Yanbian. It was marked. You can buy some Korean fudge, all in bulk. There are small white pieces and transparent soft syrup. Syrup is good for your health and it's very cheap, a few dollars a piece! Then there are spicy and hot fish and beef tendon, which need to buy "Torch" or "Mount Kumgang" brands. You can buy some fungus, mushrooms and bracken, but they are more expensive than those snacks. If you don't stay in Yanda for too long, it will only take one day to buy these things slowly. You can see some hotels on the road, as long as they are on the street, they can stay safely, but it is not clear if they are too far away. Generally speaking, they have a shower, so you can ask by the way when shopping. Can be solved. I have made a reservation. Go back to live after shopping. You can go to Tumen at six the next day. There are many buses to Tumen. A dozen dollars will do. You can take a taxi to Northeast Asia Bus Terminal, and all drivers know it. Buy tickets at any time and wait for 30 minutes at most. Yanji to Tumen takes about half an hour by car. I don't know what you are doing in Tumen. Tumen is a relatively backward city in Yanbian area, and there is nothing to see. Unless you have something to see. Otherwise, I suggest you buy a bus ticket for Hunchun directly, which will probably cost more 10 yuan. Hunchun's string is the most famous in Yanbian area, and small shops are even more violent. I regret not eating! However, if necessary, have a Tumen kebab! Different tastes. Then take a bus from Tumen to Antu to Erdaobaihe, ask at the passenger station, and then take a cable car from Erdaobaihe to Changbai Mountain. Follow the tourists to the scenic spot and you will see the ticket booth. Just wait in line to buy, and there are more than 0/00 packages in/kloc. Listen to the guide and just follow the party. Just like coming back.
I think you can contact the travel agency directly to sign up for the tour after you arrive in Yanji. If you can go to Changbai Mountain directly the next day, go to Changbai Mountain first and then go shopping after you come back.
