Hello..anyone could help me? My travel agent said when I wanna make Visa on arrival in senzhen (from HK) minimum is 3 persons, is that true? coz we only 2 persons..

If I wanna only go at morning back at night (not more than 24 hours), do I need Visa on arrival ?? confusing.

If I wanna make China Visa single entry from indonesia, can I use it to enter senzhen without making Visa on arrival?

Thanx,
