Why student suicides are on the rise in Hong Kong.

I need 3 scripts for YouTube video content (~5-7 mins videos). Each one should be around 700-1000 words. 1. Do we need teachers? The YouTube Era of Learning. 2. Why student suicides are on the rise in Hong Kong. 3. The future of Hong Kong education under China. Should also include most up-to-date news about the topic.
