Recommend a reliable one-day travel agency otz in Beijing.

Travel agencies in Beijing are better: the first is CTS, the second is China International Travel Service, the third is China Travel Agency, and the fourth is Ocean Taihe and Kang Hui Zhongxin. There are over 560 travel agencies in Beijing.

In fact, any travel agency is the same, just a little bigger. Most importantly, signing a contract is very important. Pay more attention and mention whatever comes to mind. It doesn't matter if it can be solved. If you don't hide any accusations, this is an annoying fdl.
