Chinese tourists are making their mark on the global tourism industry—literally. The picture above is a relief etched 3,500 years ago in Egypt’s Luxor Temple in Egypt. More recently, someone added the characters “Ding Jinhao was here,” as documented by an ashamed Chinese traveler who posted his photo to Sina Weibo (registration required). “We want to wipe off the marking with a towel,” the traveler wrote. “But we can’t use water since it is a 3,500 year-old relic.”

Ding, who turned out to be a 15-year-old from Nanjing, was quickly found out via Sina Weibo research. His parents have since apologized.

A tour guide surnamed Zhang told QQ (link in Chinese) that he “had never seen this sort of behavior from tourists,” and that “until recently, the Chinese tourists going to Egypt were relatively few, and their character was relatively good.”

“There’s a lot of this kind of uncivilized behavior out there,” said Zhang. “Take for example the sign outside the Louvre Museum only in Chinese characters that forbids people from urinating or defecating wherever they want.”

This is all the more alarming given the rapid rise of Chinese tourism overseas, boosted by new wealth and ever-improving exchange rates. Some 83 million traveled abroad in 2012, up from just 10 million in 2000. Reports of Chinese tourists behaving badly generally include spitting, littering, ignoring traffic laws and speaking loudly. Children are another issue: reports abound of tourists letting their children defecate in public pools (paywall) and urinate in the middle of restaurants.

Uncouth visitors have caused particular strife in Hong Kong, where 70% of the 48 million tourists a year come from the Chinese mainland. But grievances are reported everywhere. Chinese travelers are ignoring dressing customs in Thai Buddhist temples, overrunning the campus of South Korea’s Ewha Women’s University, launching drunken singsongs in Bali and generally being loud in Singapore.

The problem has become big enough that vice premier Wang Yang recently scolded his compatriots’ holiday habits. ”They speak loudly in public, carve characters on tourist attractions, cross the road when the traffic lights are still red, spit anywhere and [carry out] some other uncivilized behavior,” said Wang. “It damages the image of the Chinese people and has a very bad impact.”

In fact, China announced just last month that it is issuing a Tourism Law to take effect in October. That law will give travel agencies the authority to penalize tourists who “violate social ethics,” though it’s also geared toward cleaning up the domestic tourism industry.

In a recent blog on Tea Leaf Nation, Liang Pan, a Chinese national studying in New York, pleaded for “more understanding” for the flocks of Chinese traveling overseas for the first time, chalking much of the bad behavior up to naivety and cultural misunderstanding.

He has a point. After all, vandalism of landmarks was occurring long before the Chinese tourism boom got underway. And in many places the first nationality the world associates with “loud” and “rude” tourists is still the US. Maybe it’s just one of those things that comes with being a superpower.
