Tips for traveling between hong kong and china

Recently i had one Australian customer came to shanghai for business , he booked his flight to hong kong and from there he traveled to Guangzhou city before he flew to shanghai.Later when he arrived at hong kong airport for checking in, he was informed that he could not entry into mainland china since his visa is only one way entry. Luckily he was able  to get the visa in the following day by paying some extra money.

It is highly recommended that you applying for the multiple entry visas if you come to china often for business . Even hongkong has been returned to china in 1997 ,but there are still many regulations between them. e.g : as the mainland Chinese citizen,if we need to go to hongkong, we need to apply for hongkong -Macao passport and visa .
