Wu Xiaoyu, who was sitting nearby, saw the old man was choked by a wonton. He quickly stood up and went to the old man's side, preparing to lift him up.
The middle-aged man saw Wu Xiaoyu approaching his grandfather, ready to touch him, and immediately cursed, "What the hell are you doing? Don't move..."
Ignoring the man's shouting, Wu Xiaoyu lifted the old man, clasped his hands just below the navel, and started rapidly and repeatedly thrusting upwards into his abdomen.
This is called the Heimlich maneuver, specifically used to save people choking on food. He had learned it from watching TV in a factory in Guangdong Province, and today was his first time trying it in person.
The middle-aged man saw him holding his grandfather, flailing around, and quickly tried to pull him away, cursing loudly:
"Stop it, damn it! If anything happens to my grandpa, I'll make you pay with your life, you brat!"
