Accompanied by South Korea’s ambassador to China, Noh Young-min, Moon and First Lady Kin Jung-sook ordered a traditional Chinese breakfast that included youtiao (Chinese fried doughnut), doujiang (soy milk) and xiaolongbao (soup dumplings). /VCG Photo

Youtiao, also known as Chinese crullers, is a breakfast favorite in China. It is usually served alongside porridge, soy milk, and scallion pancakes or steamed sticky rice. /VCG Photo

Moon footed the bill using mobile payment, which is turning China into a cashless society. /VCG Photo
