When you do the square exercise, you must find the square, because the square exercise cannot be separated from the empty square. Ride a bike or take a taxi at night. Around the square, you will find a dance team dancing in Jiamusi Square.
I suggest you find a team close to home to do aerobics, not too far away. After doing aerobics, you will sweat on your way home and catch a cold easily. You can go home and take a bath as soon as possible.
