The vandalism was discovered on May 6 by another Chinese microblogger at the 3,500 year old Luxor Temple in Egypt, CNN reported.
A photography of the graffiti, which read "Ding Jinhao was here" in Chinese, was posted online on May 24 by the blogger, along with the caption, "The saddest moment in Egypt. I'm so embarrassed that I want to hide myself. I said to the Egyptian tour guide,'I'm really sorry.'"
"We want to wipe off the marking with a towel. But we can't use water since it is a 3,500 relic," the blogger said.
Ding's parents, who live in Nanjing, the capital of Jiangsu province, on Saturday issued an apology for their son, taking most of the blame and saying Ding learned a lesson, the China Daily reported.
"We want to apologize to the Egyptian people and to people who have paid attention to this case across China," Ding's mother said in Modern Express, a local newspaper.
