Help, the weather in Beijing in January

1 month is the coldest season in the north, which coincides with March 9 and is a severe cold day. Down jackets, gloves and hats are essential. In a house with heating, if the heating is not good, the indoor temperature should be 16 degrees, and 16 degrees is the lowest temperature stipulated by the government. If the heating conditions are good, it is generally 20 to 22 degrees. It is not excluded that some homes can reach 24 degrees if there is sufficient light and heating. Much better than the south. Come on, haha.
