Nearly three-fourths returned overseas students are aged between 25 and 35, and four-fifths returned overseas students have master's degrees or above, according to a white paper released on Sunday.

The white paper, China Overseas Students White Paper, was issued by Liepin Overseas -- a branch of recruitment agency liepin.com, and Beijing-based Providence Academy at a forum in eastern Chinese city Hangzhou.

From the educational background of returned overseas students, business administration and finance are the two most concentrated majors, accounting for 4.22 percent and 3.98 percent, respectively, according to the white paper.

With absolute salary advantage, the securities and rapidly developing internet-related industries are first choices for returned overseas students. In 2019, internet-related industries surpassed securities, attracting 17.21 percent of students.

Chinese enterprises have narrowed the gap of salaries with those of companies in developed countries to attract top-end talents. For instance, the average annual salaries have reached 356,700 yuan ($53,968.71) in Shenzhen, 349,600 yuan in Beijing, 328,200 yuan in Shanghai and 295,300 yuan in Guangzhou.

Hangzhou has seen the average annual salary at 282,800 yuan, with the largest annual increase of 31.84 percent, followed by Beijing of 30.09 percent.

Some 76.52 percent of returned overseas students are satisfied with their current work, with the highest figure of 87.91 percent in Shenzhen, 84.14 percent in Hangzhou, 80.53 percent in Shanghai.

Shanghai, 30.93 percent, and Beijing, 25.26 percent, have become the top destinations attracting returned overseas students, with Hangzhou, 21.87 percent, taking the third spot.
