How much is the plane from Suzhou to Harbin in early August? Which airline is cheaper?

I checked the cheap flights and prices of Harbin Pudong on August 1 and 2/for you as follows:

MU5643 PVGHRB Pudong to Harbin 08: 10 10: 50

MU56 13 PVGHRB Pudong to Harbin 08: 50 1 1: 55

MU56 19 PVGHRB Pudong to Harbin 2 1: 00 23: 50

The price of the above three shifts is: 880+ tax included 180= 1060 tax included.
