Now, Thailand is popular among more and more tourists from the world, including Chinese. In Thailand we should do the things as Thais (泰国人） do. When we can't do all the things as Thais, we should at least learn and respect(尊重) their customs (风俗). Here's something about their customs.
Personal appearance (外表) is very important in Thailand as a sign of respect for other people. Your clothes should be tidy, clean andfreefrom holes. Shorts and sleeveless (无袖的) shirts are not welcomed in churches (教堂.) Remember that you will need to take off your shoes when entering rooms, so don't wear shoes that are slow to get on and off. The rules are even stricter(严格) with foreign visitors, so even if you see a local in shorts, it's not OK for everyone.
It's not polite to touch a Thai on the head, including children. At the same time, don't touch people with your feet, or even point with them because they think feet are dirty and low.
If someone is sitting with outstretched (伸出的) feet, don't step over them, because this is very rude. It could even make people angry. Even if the person is sleeping, it is best to go around until he or she notices and lets you go out.
