Beijing announced on May 11 that people can use three gestures to show their objection to those smoking in public venues. One is to put a hand over one’s mouth to tell a smoker that one minds him or her smoking. Another is to stick two fingers beneath the *palm of the other hand to ask the smoker to stop smoking, and the third is to hold a raised palm out toward the smoker to say no. The announcement came 20 days before the capital’s strictest smoking ban takes effect on June 1.
