The basic transmission form of the Olympic flame is that the torchbearer passes it to the main venue of this Olympic Games. In this long "journey", the flame will be passed indirectly by each torch. The first torch every day is lit by the Olympia flame stored in a special torch. Each torchbearer will light the torch in the hand of the next torchbearer after running a relay distance with the torch in his hand until he reaches the celebration site of the relay terminal. According to Olympic etiquette, the celebration at the end of the relay race every day is simple and grand, usually lasting 1 hour. It consists of torchbearers who lit the torch platform at the celebration venue, representatives of the torch relay host city and the Olympic Organizing Committee, the broadcast of the torch relay propaganda film and cultural performances showing local cultural characteristics. The kindling lamp is specially used to store kindling. After the relay, the flame was kept in the flame lamp to rekindle the first torch when the torch relay started again the next day. In order to ensure the dignity of the torch and the purity of the torch relay, it is necessary to keep the torch burning continuously during the torch relay. Flames and kindling should be properly protected. Once the torch is extinguished, it must still be lit with fire and kindling.
With the development of science and technology, the torch is lighter and lighter, and the combustion system is more convenient and perfect. Usually, the gas tank is placed inside the torch to ensure that the burning time is 15 to 20 minutes. The torch of Beijing Olympic Games is 72 cm long and weighs 985 grams. Combustion time15min, flame height 25-30 cm at zero wind speed. It can be recognized and photographed in strong light and sunlight.
