© JIGUANG Confidential. All Rights Reserved. 2 Key Findings Due to the spread of Coronavirus (2019-nCoV) during the Chinese New Year Holiday, the majority of mobile users across the country stayed at home to avoid outdoor activities, leading to a sharp rise of screen time of 26%. Online education, remote working, cooking and dining at home, indoor entertainment and news reading apps saw a large spike in usage.

Instant Messaging Apps - DingTalk - an office app, usage fell to recent lows during the holiday. However, after the holiday, many people worked from home, making the app rebound over 100% and rising.

Weibo - Weibo’s DAU growth during the holiday beat that of last year because of the clicks on coronavirus headlines. Time spent also increased over 50% compared with that of the same period last year.

News Reading Apps - Baidu’s DAU and time spent had a steady increase after the holiday as people mainly used it for searching on the coronavirus updates. DAU and time spent of Tencent News and Toutiao started to rise even before the holiday. Tencent News has released a daily tracker of the disease, which led to DAU increase of almost 50%.

Short-Video/Games/Streaming Apps - Benefited from the super long holiday, entertainment apps gained more compared with the same period of last year. Tik Tok/Kwai/Xigua TV’s marketing campaigns on New Year’s Eve were well received. Video streaming apps like iQiyi also saw much increased traffic. People who are stuck in home killed time using these apps to reduce the possibility of cross-infection.

O2O/Food Delivery/Ride sharing Apps - These segments were impacted most by the disease. There are restrictions by the government to go outside, so demand for ride sharing decreased sharply. The demand will resume once the disease outbreak ends. They are also lending a hand during this time. Meituan/Ele.me are helping citizens and hospital staff who are in need by delivering food and vegetables. Didi is giving free rides to people who are in need.

Online education/Fresh Food E-commerce - These segments had a U- shape curve and saw an abrupt increase of multiple times normal DAU. 3 Background In January of 2020, a SARS-like virus outbreak originating in Wuhan is spreading into other parts of China
