Two people in Anyang, Central China's Henan Province, were found with the Omicron variant on Sunday, the same transmission chain with that found in Tianjin. 

One of the two is a college student who returned to Anyang from Tianjin on December 28, 2021. 

Tianjin is now fighting a real battle against Omicron after two COVID-19 cases were found with the more contagious variant over the weekend.

Anyang has asked any resident who travelled to Tianjin's high-risk areas to report to local officials. 

Sanhe city of North China's Hebei, 54 kilometers from capital Beijing, also reported a close contact of a confirmed case in Tianjin. It remains unknown if the person, who is now under quarantine, has the virus.

In order to prevent further spillover, the railway authority has suspended selling tickets from Tianjin to Beijing. Only some inter-city train tickets are still available to buy, media reported. The train ticket platform shows that all tickets from Tianjin to Beijing are either sold out or suspended from selling. Tickets from the capital to Tianjin are still available.

Cities in Henan, such as Zhengzhou, have been also battling with the outbreak during the past week, caused by the Delta variant. The central China's province recorded 60 new cases on Sunday.
