The next morning, Douyin's growth data was released. It had gained 2.3 million new users the previous day, bringing the total to 5.7 million.
Meanwhile, Little Yellow Bike's marketing expenses had surged again, up 63% to over 13 million in a single day.
Chang Wei was inexperienced, not stupid. He immediately sensed something was wrong.
He had thought 8 million a day was the peak, but it turned out that was just the beginning.
The data and tech departments of Little Yellow Bike were notified and rushed back to the office, grumbling and cursing.
'What the hell is this!'
'Don't they know it's a holiday?'
'Does the boss have no sense of boundaries?'
'What kind of decent person calls people back to work overtime on Labor Day?'
Half an hour later, the Market Department staff also trudged into the office, dejected, to help the data and tech departments investigate the problem.
By two in the afternoon, no one had found the source of the issue.
