Taking photographs or videos of military installations is prohibited. Most museums, palaces, or temples will not allow photograph to be taken,
notably the main pit of the Terracotta Warriors, but some institutions permit it on payment of a fee in advance.
As the atmosphere in China is often hazy, filters are advisable. Colour print film is widely available, black and white or slide film much less
so. Video film can be found but not always readily. All security X-ray machines on Mainland China and at Hong Kong airport are film-safe. Cameras must
be declared when arriving in China. If video or movie cameras are for professional use, special permits must be claimed.
Road Names may have suffixes to indicate north, south, east or west, and additionally, to indicate the middle section. The middle section is called
zhong; nan means south; bei, north; dong, east and xi, west. A main road is lu or dao, smaller is jie. A small lane is named xiang.
Travelling with children in China is not difficult. If with toddlers or babies, note that disposable nappies and baby food in jars are not readily
available. Big hotels offer childcare for a fee. On trains and planes, children travel at reduced cost.
