When you travel in HongKong，you must be careful of the traffic rules，because the traffic keeps to the left and it’s different from that of the interior（内地）of China．
Before crossing the street，you must look to the right and then to the left. If the
traffic lights are red，the traffic must stop, people can cross the zebra line．If the traffic lights turn green，the traffic can go，people must not cross the road．
In the morning and in the evening，when people go to or come from work，the streets are very busy．The traffic is the most dangerous．
When you go somewhere by bus in Hong Kong，you have to be careful，too. Do remember the traffic keeps to the left．Have a look first，or you may go the wrong
way．
