Noting that activity in mainland China peaked from 10PM to to 12AM, WeChat states that it processed 10 million messages in one minute.
That figure dwarfs the one released by Sina Weibo, which stated that it processed 863,000 tweets within a single minute on the same day.
Granted, it’s not entirely appropriate to make exact comparisons without seeing numbers and timelines side-by-side, and the two social networks serve slightly different purposes (WeChat works better as a person-to-person messaging app, while Sina Weibo is more open and public).
WeChat also states that on the eve of the Lunar New Year, Beijing was the most active region in China, followed by Guangdong, Zhejiang, Liaoning, and Jiangsu provinces. Collectively, activity from users in these regions accounted for 42 percent of WeChat’s global activity.
Meanwhile, users sent twice as many and received three times as many messages on the eve of the Lunar New Year in 2014 compared to the same event last year. WeChat also notes that it saw a significant rise in the number of video messages it processed, which it attributes to the “quiet arrival” of 4G in China."
