Open the door, turn on the lights, kick the shoes, throw the bag, all in one go.Zhang Xiaowen moved the heavy ladder from the balcony to the bathroom little by little, tried his balance, and climbed up the ladder carefully. Suddenly his feet slipped, and he screamed "ah", and fell back heavily on the tiled floor, motionless.
