SevenContinents:

Thesevencontinents,recognizedglobally,are:

Asia(亚洲): Thelargestcontinentbybothlandareaandpopulation,encompassingavastdiversityofcultures,landscapes,andclimates.FromthetoweringHimalayastothefertileplainsofChina,Asia’sgeographicalrangeisunmatched.Itsdiverseecosystemssupportabreathtakingvarietyoffloraandfauna,anditshistorystretchesbackmillennia.

Europe(欧洲): HistoricallyandculturallyintertwinedwithAsia,Europeisoftenconsideredaseparatecontinentduetoitsdistinctculturalandhistoricaldevelopment.Knownforitsrichhistory,vibrantcities,andadvancedeconomies,Europeboastsdiverselandscapes,fromtheruggedAlpstothepicturesquecoastlinesoftheMediterranean.
