This Tiananmen thing was basically 24x7 in the whole summer 1989 on TV. It also has impact on many people's daily life. For example, if you're in hotel, you likely see police knocking your door to search at mid night. If you work, Saturday afternoon is mandatory time for all employers to organize employee meeting to learn official report about Tiananmen square (before 1993, Chinese worked 6 days a week, but Sat usually is slow/light working day). It lasted at least through 1989.
