Hi, Me (a SPR with China Passport) and my husband (Singaporean) plan to go Hong Kong and mainland for vacation. We are going to stay in Hong Kong for 3 days and mainland for around 20 days. What are the travel documents we need? and what is the easiest way for us to obtain them? I checked online, the instructions for applying a Hong Kong entry permit is like 100 pages long and I am still clueless about how to apply it and the charges. Thanks!
