Route 2: First, buy ginseng from Beijing, regardless of the price, and sell it in South Xinjiang (it is absolutely profitable, and it is sent by sects in Beijing), then buy agate or honey from South Xinjiang and sell it in Dawang Village (regardless of the price), then buy it from Dawang Village (all three can be bought), and return to Beijing from sects to sell it (only earning no loss), and then make up the ticket.
According to personal preference, you can choose one of the routes. ? It's very hard to write. I hope the landlord will adopt it. Thank you.
