Visa for travel to Shenzhen via Hong Kong

Canadian citizens can easily obtain a 5 days visa for a visit to Shenzhen ONLY in the Luohu Immigration building. The visa office is located on the first floor (up the escalators on your left) immediately before the Chinese Immigration counters. Photos or appointment are not required and you just need your passport and to fill in a form and you will receive your visa in 5 minutes if there is no queue. The cost was 168 RMB when I was in Shenzhen in June. Please note this visa does not allow you to travel outside Shenzhen.
