Ma Guoliang's noodle restaurant was closed for business after a nearby residential community in Liwan district in Guangzhou, the capital of Guangdong province, had been locked down as the city tightened measures to fight the COVID-19 outbreak.

Ma, 24, from Northwest China's Qinghai province, made dozens of bowls of beef noodles at his restaurant, which were later delivered to medical workers at a local control and prevention command center. 

"I have been thinking about doing something to join the battle against the new wave of the coronavirus outbreak," Ma said. "I also donated bottled water and quick-frozen dumplings to medical workers, who are really working hard in the fight against the coronavirus outbreak." 

Guangzhou has further increased its measures to fight the coronavirus after two subdistricts in the city's Liwan district were elevated from medium-risk to high-risk areas.

Residents in the subdistricts of Baihedong and Zhongnan are not allowed to leave or enter the two areas, as COVID-19 cases and asymptomatic carriers detected in the subdistricts continued to rise. 

Like Ma, a large number of medical workers, police, volunteers as well as social forces have been engaged in combat with the COVID-19 in Guangzhou, since the city reported its first local confirmed case in a new wave of the coronavirus outbreak on May 21.

Additionally, an increased number of residents and companies also joined the battle against the new wave of the coronavirus outbreak.

In a latest development, Guangdong-based Sunrich Group donated over 200 boxes of bottled water to frontline medical workers, volunteers and residents in Guangzhou on May 31.

"We hope to do our part and work together with the city to win the battle against the pandemic," said Amy Deng, executive assistant manager of Sofitel Guangzhou Sunrich.

More than 60,000 volunteers across Guangdong joined the battle against the outbreak on May 21-30 by being engaged in organizing nucleic acid tests and delivering necessities in closed-off communities, according to the Guangdong Provincial Committee of the Chinese Communist Youth League.
