俯臥撐 (fǔwòchēng): (do) push-upsBacklash against this suspected cover-up resulted in the Weng’an riot.
The young man was alleged to have raped and killed a 16-year-old girl. In an attempt to quell the outcry, police claimed that the boy and girl had been arguing along the bank of a river. When they had calmed down, the boy began to do some push-ups. After he had done three, he heard her say, “I’m going,” after which she jumped into the river and drowned herself.
Few believed the police account, and a riot ensued involving tens of thousands of people. As the phrase “I was doing push-ups” spread, it has shed much of its political connotation. It no longer has just one definition: sometimes it means “minding one’s own business,” while other times it refers to a nonsensical cause of death.
