This tweet was posted at 6:30 in the morning, when most people were still immersed in the sorrow of the black swan disaster. My trader instincts made me realize this wasn’t a natural disaster but human error. As the day went on, more and more people woke up to this realization. After being criticized across both Chinese and English communities, He Yi disappeared for over ten hours and still hasn’t explained the cause of the incident, only promising partial compensation. So stop praising them for 'responsibility and accountability.'
