Do you feel happy? What are the factors closely associated with happiness? These are among listed questions of an online survey jointly held by the China Population Communication Center and Durex.

The survey is the first of the kind in the nation featuring a highly happening society about the family values and happiness and the coming results are expected to help decision makers better fine tune relative policies so as to improve people’s life and happiness, said Zhang Hanxiang, who heads the China Population Communication Center.

Meanwhile, specialists would be sent by the center into communities and enterprises, lecturing people on keys to happy family like pressure relieving courses, health and body preservation tips, and child education, he noted.

Also, the survey includes questions concerning sex, as "quality sex is necessity of happy family life," according to Zhang.

In fact, durex, which funded the survey, kept releasing a global survey on sexuality for many years in row.

According to results from the 2007 survey, the Chinese have sex for the first time at an average age of 22.1 years, about 5 years later than the global average.
