The respect to the king

Every time when I go for a movie in Bangkok, it reminded me of respect. Just before the movie begins, the national song will be played with the king's images on. At this time, we are expected to stand up and give our respect. I don't remember anywhere in other Asian countries that we do that to our leader. The token just reminded me how faithful the people are to their beloved king. After the national songs ended, instead of rushing to seat, you may see some even bow their head and then seat. If only other countries can gain such a respect, it's really tell me something how to gain respect and be respected.
