Above: The 8 finalist logos for the China Mars 2020 mission competition (CMEP).The eight finalist names, many coming from Chinese mythology, are: Fenghuang (phoenix (凤凰)), Tianwen (study of heaven (天问)), Huoxing (Mars (火星)), Tenglong (flying dragon (腾龙)), Qilin (a mythical chimerical creature(麒麟)), Zhuque (a mythical bird (朱雀)), Zhuimeng ('chasing dreams' (追梦)) and Fengxiang (flying phoenix (凤翔)).
Many of the eight logos focus on the character '火', which means fire and forms part of the Chinese name for Mars, '火星', literally 'fire star', with the name due to the planet's colour.

2020 torch relay: The first Olympics originally scheduled for Japan were in 1940 set to be the first country to carry on the torch relay ritual:
Had the 1940 Summer Games been held, a never-before used method of bringing the Olympic Flame from Nazi Germany to Japan was proposed - by air delivery, in the purpose-built Messerschmitt Me 261 Adolfine long-range aircraft, which was designed to have a maximum range of some 9,500 km (5,900 mi) unrefueled.[13]
