hello, i m going to harbin on 5 or 8 feb.2016, i m from Malaysia.

The previous records show that the temperature may range from -5 F to 5 F. It will be extremely cold. You need to bring winter clothes, such as down jackets, sweaters, snow boots, thermal underwears, scarves and sloves. Maybe you can bring some cold fighters to avoid influenza.
In addition, you can still see the ice sculputures at that time. People will preserve them well for the Chinese New Year. Don't worry.
