re : to China
1. Entry Permit (for China) - online book an appt, say Sat, 15mins completed. 2 weeks for processing, so you can do it ar.
2. Passport & ID Card - fill the form, I can't remember how many weeks for processing, I guess 1 month, so if you can do it like tomorrow, means can collect back the passport in mid-Jan.
3. HK Entry ('wun kong ching')
should be smiliar to Passport, do it together w. passport & ID Card.
You can call 2824 6111 HK immigration to check the details.
