脑洞大开来不及延期的话, 23号晚12点前入闸。for example, T2/3 @PEK
My wife and I stayed overnight at the Terminal 2 lounge after a flight from Detroit. The cost was 480RMB ($76USD). The next day we had a domestic flight to Guangzhou, China then on to Kathmandu, Nepal. Before I left home, I contacted the Chinese Embassy and they said that as long as I did NOT leave the airport property, I did not have to get a Chinese VISA.
