What's the weather like in Changchun on the 27th? What should I wear? Where can I buy special products?

It's very cold. The thicker you wear, the better! Must be a down jacket. Ginseng goes to Tongzhi Street, and there is Ginseng Street. Take a taxi to the fourth sub-bureau, and the driver knows it. Buy fungus and mushrooms and go to Wal-Mart. Ginseng has all kinds of money, from 5 yuan, from 50 to hundreds.
