After the toilet poop is, where can I flush the poop out?

Generally, above the toilet tank, there will be two semi-circular keys together, press any one of them to get out of the water, and one is on the side of the toilet, and there are two forms on the side, one is the downward pressure type, and the other is the knob type, the two forms are also very different, the knob type is like a switch handle, this is a sitting toilet.

Squat toilets have a press type, a water-saving water tank type (similar to a sitting type), a pedal type, a knob type, and an automatic infrared sensor type (no manual type)...
