They do not touch on the real reasons for these amendments. One is to look tough and nationalistic to their domestic audience. Another is to inflict psychological fear in Taiwanese and those who support Taiwan internationally that the CCP could potentially be coming for us, not only in China, Hong Kong and Macau, but in 45 other countries as well.

Hey guys did you know the real reason is to look tough and nationalistic and not (among other reasons) the US attempt to have an unsinkable air craft carrier to project power

I wonder why this extends into the mainland. Could there be historical context?

When the CCP is planning another dramatic change of the status quo, they go out of their way to also pick a date when it will send a message.

For example, often when countries switch diplomatic recognition from Taiwan to China, the announcement will be timed to pack a punch, such as Nauru making their announcement right after William Lai (賴清德) won the election. Similarly, there was no way the enormously complex live fire training exercises China launched to upend the status quo could have been planned in the tiny window of time from the-then US House of Representatives speaker Nancy Pelosi’s announcement she was to visit Taiwan and her arrival. They had planned it long in advance, — her trip was merely an excuse. To this day, it is common to see the Chinese military gray zone menacing behavior that continues being traced to Pelosi’s visit, almost as if she were somehow to blame.

Hey trust me they've been planing this for a long time. And these misogynists of course blame girl queen Pelosi. Not like China denounced the visit in advance. Classic reversal of cause and effect.
