In some countries, the national anthem is played to students each day at the start of school as an exercise in patriotism, such as in Tanzania. In other countries the state anthem may be played in a theatre before a play or in a cinema before a movie. Many radio and television stations have adopted this and play the national anthem when they sign on in the morning and again when they sign off at night. For instance, the national anthem of China is played before the broadcast of evening news on Hong Kong's local television stations including TVB Jade. In Colombia, it is a law to play the National Anthem at 6:00 and 18:00 on every public radio and television station, while in Thailand, "Phleng Chat Thai" is played at 08:00 and 18:00 nationwide (the Royal Anthem is used for sign-ons and closedowns instead).
