Unlike table tennis (乒乓球) or badminton (羽毛球), which have long been massively popular and accessible “national sports” in China, 网球 (wǎngqiú) is a more recent and aspirational arrival. Its status is comparable to golf in the West—historically seen as a sport for the affluent, associated with a modern, urban, middle-class lifestyle. The sport's popularity exploded in the 2010s, almost single-handedly due to the success of tennis superstar 李娜 (Lǐ Nà). Her Grand Slam victories (2011 French Open, 2014 Australian Open) made her a national hero. She represented a new kind of Chinese athlete: individual, outspoken, and successful on the world stage outside the traditional state-run sports system. Her fame transformed 网球 from a niche sport into a mainstream interest, inspiring millions of children to pick up a racket. Today, major international tournaments are held in cities like Shanghai and Beijing, and playing tennis is seen as a fashionable and healthy activity.
The most crucial thing to know about using 网球 in a sentence is the verb that goes with it.
