That was the case in the 1980s and 1990s, as well as part of the 2000s. However, it's no longer true. How the CCP has dealt with Hong Kong is the opposite of patience. All they had to do was wait until 2049, or even 2040, because after the 50 period legally they were entitled to do whatever they wanted and in the run up to that they could have justified converging HK's politics with the mainland. They could have bought the protesters off with an independent investigation into police brutality for now, maybe made some concessions on electoral reform in the next 5 years. Instead they went full oppression-mode because they couldn't help themselves. Zero patience.
What they've done is short-sighted not just because it ruffled feathers in countries like the UK, US, Canada, etc, but it also sent a message to Taiwan about what they could expect if unification took place. That was an incredibly dumb thing to do, as it helped the pro-Taiwan DPP win another double-election, and even made the KMT say that one country-two systems was no longer a viable political solution.
Following on from that, rather than opening talks with the DPP and make it think that the CCP could be changing its view and thereby playing a long game where Taiwan becomes ever more reliant on China, the CCP has stepped up military threats. That can only worry Taiwanese and make it easier to justify unpopular military reforms as well as force the Taiwanese government to seek to make itself less reliant on the PRC. That doesn't benefit China.
Finally, the wolf-warrior diplomacy has been an epic failure. It's just antagonised other countries more and more. For example, read this article from the pro-Beijing SCMP.
Ambassador Cong Peiwu’s remarks on the safety of 300,000 Canadians in Hong Kong may have stiffened the Trudeau government’s stance, and emboldened China hawks.

Any official with half a brain would have told this idiot that what he was going to say was dumb. So either the CCP has no diplomatic staff with brains or they're too terrified to tell their bosses that they don't know what they're doing. Again, no patience.
2019/2020 was not the time for China to "reveal" itself. If the CCP were playing a game of absolute patience they'd wait until we're all dead, like 2100 or even later, because by then the Chinese economy and military theoretically could have completely eclipsed the US to the point where the power balance was like China-Taiwan now.
