Shenzhen five-day VOA

Hi,

Need your further information regarding Shenzhen VOA. Me and family (totally 6 people) are going to visit Shenzhen for vacation. We'll do a private tour, not join a travel agent. Once we landed in HKIA, we continue our trip directly to Shenzhen.

In ths case, should we apply group VOA or personnal VOA once reached Louhu Port? Pls help to explain to me since it's the first time I'll travel to Shenzhen privately, not joining a travel agent.

Tks & Rgds,
Sisca
