If it is a foreigner, ginseng antler-that is, ginseng, velvet antler, ganoderma lucidum and other specialties, there is a market to sell this kind of thing in the underground passage of Shenyang Railway Station. There is a wholesale market of ginseng antler on Nanwu Road, about 600 meters south of Shenyang Railway Station, and the price can be lower.
There are also dried vegetables and dried bacteria in the northeast. For example, dried products such as "hazel mushroom" and "Hericium erinaceus".
Anyway, I think ginseng is the best. One is not too expensive, and it's good to give it away.
If you are a mainlander, you can also choose seafood-such as sea cucumber. Many such shops.
