SHANGHAI, Jan. 29 (Xinhua) -- Traveling is an inseparable part of happiness among Chinese people, according to a report.

About 80 percent of all respondents think that family tours can bring happiness, and 96.5 percent of those surveyed crave family tours, according to the report jointly released by the China Tourism Academy and China UMS.

Last year, a total of 5.54 billion tourists traveled within China, up 10.76 percent year on year. The tourists generated a revenue of about 5.13 trillion yuan (762 billion U.S. dollars). About 148 million Chinese residents traveled overseas in 2018, up 13.5 percent year on year.
