Enquiry About Re-entry Visa

[TropicRain]

I am holding the passport of P.R. China. I am going to fly to Bangkok, where I can get Visa-on-arrival at the airport. Then I am going to travel to Siem Reap overland and back to Bangkok. But I heard I cannot get the Visa-on-arrival at the border between Thailand and Cambodia when i re-enter Thailand from Cambodia and have to apply re-entry visa. But how to do so? Or is there any other kind of Visa I can use to enter Thailand from Cambodia by land?

Thank you so much!

For citizens of the PRC an outbound airticket must be shown to get that 15 day non-extendable tourist visa on arrival at Bangkok International Airport.
