Siem Reap, what type of adapter plug should I use there?

No conversion required, just like in China.

Pay special attention to preventing theft. There are many hotels near Siem Reap Old Market, and most of them have attentive service, but I would like to remind Chinese people who are traveling to Angkor to choose Angkor carefully. When money was taken away from the suitcase in the room, the hotel ignored it and even cleaned it. They also denied that hotel staff had ever entered the room, which was very infuriating. The Angkor Riverside Hotel bullied the Chinese. It was heart-breaking to see how many aid projects in Cambodia were funded by China. And there is no anti-mosquito equipment at all. I am tired during the day and cannot sleep at night because of the noise of mosquitoes. Lessons of blood and tears
