Nanjing gets defensive about city wall after claims by Xi'an

The Tourism Administration Bureau of Xi'an has apologized for suggesting that while its city wall has stood for more than 600 years, walls in Nanjing and Beijing had disappeared long ago.

After the comment was posted on the micro blog of the Tourism Administration Bureau of Xi'an, Shaanxi province, a number of residents in Nanjing, Jiangsu province, complained online that the ancient city wall in Nanjing not only still stands but has been around longer than the one in Xi'an.

"I do not know what you mean that the ancient city wall in Nanjing disappeared," a Nanjing netizen said.
