Go to Beijing for about two months. Is it cold?

1, with coat, underwear and long coat.

2, the standard temperature, more than 20 degrees, if the heating is broken, there is no temperature.

It's cold outside at night, so wear a thick coat. You can wear underwear in the house.

If there is no heating, I advise you not to wear a shirt. If you have just come back from the North Pole, I guess you will get used to wearing shirts.

You're welcome.
