China has halted in-person teaching and restaurant eating in an area in the heart of Guangzhou, raising fears about the potential for disruption in the southern Chinese industrial metropolis, which is home to roughly 19 million people.

Guangzhou is one of China's major cities, and in addition to being a commercial center, it has the most restaurants in the country. As a result, experts have raised worry about the potential economic impact that the new limits may inflict in the near future.

Guangzhou has seen a significant increase in cases in recent days, with the official number reaching 69 on Sunday. While no deaths were recorded in the region, Communist Party leaders opted to impose limitations ahead of time in anticipation of a future shutdown.

Other parts of the country have also seen an increase in instances, with official statistics indicating that Shanghai and the technical powerhouse Shenzhen have recently been the worst afflicted.
