During the 2019-20 coronavirus pandemic that broke out first in the city of Wuhan in Hubei province, the phrase "Wuhan jiayou!" was a common expression of solidarity throughout social and news media but also in public with the city which went under lockdown. Videos soon surfaced online on January 23 of Wuhan residents chanting the phrase, roughly translatable to "Stay strong, Wuhan!" or "Keep on going, Wuhan!", through of their windows to neighbours with many joining in to the chorus to echo across the high-rise buildings of the city.[8][9]
The phrase was also used to express international solidarity with Wuhan. Relief boxes of face masks sent to Wuhan because of a shortage by its sister-city of Oita in Japan were labelled with "Wuhan jiayou!"[10] On February 2, the UAE declared "We support Wuhan, and the Chinese communities around the world" and projected the phrase "Wuhan jiayou!" onto the Burj Khalifa in Dubai as a message of solidarity.[11]
