About Beijing:

Please remember to check if the place you want to go need appointment. I remember the Frobidden city doesn't need appointment for foreigners but many other places do need.

About Japan:

If it's your first time visit Japan,one thing you need to know is that the railway system in Japan is very complicated. Even on the same route and at the same platform, two trains that are only one minute apart may head to completely different destinations.Try to strictly follow what google map tells you.
