Hi, I will travel from Hong Kong to Shenzhen, can I get visa on arrival in Shenzen? How much it cost? I'm travelling in group of 6 (4 adults & 2 child), we stay in HKG but we want to take 1 day trip to Shenzen visiting WOW, Chinese folk Culture & Lo Wu mall, is it easy to take taxi from chinese folk culture to the mall/train station to go back to Hkg. Thx.
