Islam is the state religion in Malaysia. According to this, the Islamic strict regulations are all central to and dominant in Malay culture. We can notice especially from the way they dress which is entirely polite. Malaysian cultural outfits are quite formal. Most men wear long sleeved shirts, tie neckties and wear long pants. In case of formal events, men should wear suits. Most women wear knee-length skirts or long pants and wear shirts which entirely cover the upper body (from neck to waist). Similarly, thai cultural outfits' manners are also the things that every thai people should think of. We dress politely in many kinds of situation like going to work, going to a religious place or going to a hospital. For example, when we go to school, we have to wear school uniforms. In other words,There are also many rules about wearing clothes in Thailand. It depends on the place where you are going or the things that you are going to do. People who follow the rules have good manners.
In my opinion, every person should care about manners as much as possible. Because it shows respect and makes a good progress in everything.
