You made it sound like you are going deep into the depth of Africa, rather than modern China.Originally Posted by 31770
Most of your precautions seems good, i would add on a diphteria/tetanus/pertussis rather than just tetanus vaccine.
Using bottled water should be safe. One ought to boil any water in china anyway.
Using beer to brush teeth is a no no.
Anyway, enjoy your trip.
Do not be afraid, learn the local culture and cuisine, otherwise, it would just be a waste of your trip there.
