I intend to visit Lijiang from 20 jan till 27 jan. How's the weather that period?

According to previous weather statistics, the temperature may range from 30 F to 50 F during that period of time. It will have several sunny days. You are suggested to wear overcoats, sweaters, pants, boots, thermal underwear and scarves in order to adapt large temperature difference.

You don't need to join in a travel agency when touring around this area. It's fine to tour by yourselves.
