Solution: Use A wire to connect E- and GND I read the datasheet of HX711, and found a design fault of the hx711 moudule in the market. In the picture above, we can see that the pin-5 is AGND, The picture below shows the recommended application in it's datasheet. It should be connected to GND, but the module dosen't do that. But we can still use the module, because the current can flow back via SCK pin, when it's low level. However, it's not stable.
