Thailand is a very beautiful place, full of state attractions. But tourists who come here for a vacation, must comply with local rules and regulations, otherwise you may lose respect in the eyes of the locals or, in the unfortunate case, even go to jail.
First, in Thailand, the king is respected, and if things are bad about the royal family, or just making a bad move towards them, every locals consider for their own violation, the more that the law prohibits this, and you may have problems with representatives of the authority.
Also in Thailand you have to respect the Buddhist religion and the holy places. If you come to a Buddhist temple, try dressing as simple and as close as possible. In the temple you have to sit so your feet do not "see" towards the Buddha.
In Thailand, there is no expression of open feelings in the relationship between men and women. Even married people can not take freedom in their minds, behave very simply.
In Thailand, the head is a sacred part of the body. And indecent, for example, to caress a child in the head. This is prohibited even if you have a good relationship with the parents of this child.
In Thailand, it is customary to exercise restraint in the manifestations of emotion in all things. You can not express your anger in public. This is just the height of the inaccuracy and if your child is destructive in front of the Thai, you need to try to calm him down with a calm method. Punish the child for all sorts of anger.
If you are invited to visit, then with the rules of decency you need to eat more slowly than the owner of the residence. It is considered very indecent if a guest eats faster than he does.
In Thailand, it is customary to read the elders, so try to treat people older than you, with great courtesy.
In Thailand there are restrictions on imports and exports. You can take one camera and one video camera with you. Exports from Thailand forbidden products made from bones and rare animal skins, and if you buy souvenirs at the store, then customs should provide a certificate that allows you to take these items. It is forbidden to import liters to countries with obscene content, weapons, rare representations of the animal world. Most importantly, do not try to import narcotic drugs or use them during breaks. Your life may end prematurely.
In fact, all this just looks very tight. Thailand is a tourist friendly country.
