The North American Chinese Invitational Volleyball Tournament (N.A.C.I.V.T.) is held every Labor Day weekend and features men's nine-man (9-man) and women's 6's volleyball teams. The tournament is generally held outdoors and played on pavement, with the courts typically set-up in a large parking lot or even on the streets. Because of changes in climate the tournament can also be held indoors (ex: Convention Centers.) It is very much a cultural phenomenon; two-thirds of the players on each team must be 100% Chinese, and the rest must be of Asian descent. The inaugural tournament was held in Boston in 1944. There are teams from Boston, Maryland, Los Angeles, Chicago, North Carolina, Houston, Montreal, New York City, New Jersey, Philadelphia, San Francisco, Houston, San Diego, Toronto, and Washington, D.C..
Each year there are also mini tournaments held in Toronto, Boston, New York City, Philadelphia, Washington D.C./Maryland and San Francisco leading up to the annual NACIVT.
The 70th NACIVT (2014) will be hosted in (San Francisco Host) Las Vegas, Nevada. Over the 3-day Labor Day Weekend.
The men's 9-man portion of the NACIVT is the subject of a documentary called 9-Man 1 that was completed in 2014 and had its world premiere at IFFBoston on April 27, 2014.
