Recently, foreign media reported on the Chinese work ethic, such as The Guardian article "How hard does China work?" on Oct. 6, suggesting Britons needed to pull up their socks and work hard "in the way that Asian economies are prepared to work hard". On Oct. 8, Singapore’s Lianhe Zaobao cites The Guardian’s statistics, saying the average Chinese worker puts in somewhere between 2,000 and 2,200 hours each year.

The earliest survey data is published on Wall Street Journal last year. It claimed, citing official statistics that nearly 85 percent of migrants worked more than 44 hours a week, earning an average of just £270 per month.

China is one of the countries with the longest average working hours in the world, equivalent to the level of the countries such as the UK, Germany and France in the 1950s, according to data. In addition, survey data reflect the general working hours of European and American countries per capita is shorter than of developing countries.

According to figures from the Organization for Economic Co-operation and Development, in 2013, working hours in Germany and France were 1,388 hours and 1,489 hours respectively, well below China’s per capital working hours at the same period. Compared to the UK average of 1,677 hours last year, the average Chinese worker put in 320 more hours last year.

Why do Chinese workers have to put in longer hours than their counterparts in European countries and the United States? Director of Research at the Guangdong Academy of Social Sciences, Ding Li, said that China's per capita level of work depends largely on the strength of the domestic economy.

Chinese workers have to work longer hours than their peers from the more developed countries, such as the UK and US, because in China the average wage is low, while the domestic prices are relatively high, noted celebrity financial expert Larry Hsien Ping Lang in 2013.

Last year, the labor market research center at Beijing Normal University released a report, noting employees in 90 percent of industries in China work over 40 hours per week. Those working in the construction industry, resident services, repairs and other services have a working week of over 49 hours and the longest hours in China are worked by those in hospitality and catering, racking up over 51.4 hours.

For more than half of all industry sectors, including accommodation and catering industry, employees do over four hours’ overtime per week.

In recent years, Chinese people pay more attention to health problems caused by growing pressure from work, such as fatigue, obesity and insomnia.

However, long working hours will persist for a certain time as Ding Li pointed out, because China is still at the developmental stage of chasing GDP growth and increasing total production.
