A total of 120 million students of 140,000 schools across China have resumed classes through e-commerce giant Alibaba's communication app DingTalk, the company said Wednesday.
Half of the students in the country are now attending classes through the app that was originally a mobile office tool and was adapted to offer online services for schools amid the virus outbreak, it said.
To meet the huge demand during the epidemic, DingTalk has added more than 100,000 servers to maintain the stability of the app.
