1. Electing Trump as their President was the best thing they did to their country (if you look from their perspective)
From their perspective? Let's see:
1. Over 20m Covid case, 600,000 death. Just happened in the world No.1 superpower;
2. Instead of focus on China's trade dispute, he opened fire on everyone. As the result, US has to fight alone. He wasted the golden chance (probably the only chance) to win the trade war;
3. By pissing off every US' ally, he makes it an mission impossible for any future US president to create a meaningful anti-China alliance;
4. He promised to bring back the manufacturing departments to home, but he cut federal budget on public education and public health system, which actually push up the labor cost in low and middle manufactures.
5. His public anti-China announcement did a great favor for CCP: now even those anti-CCP Chinese have to support Xi's government because they can't allow China to lose a potential war against a superpower.
Yes, he was the best president for China.
2. Actually It was solely USA's fault in letting China become the Factory of the world. Those Chinis werent even able to produce quality steel.

It was Japanese built the first modern steel production plant in China in 1978: Baoshan Steel which made Chinese steel industry bridge 30 years tech gap.
It was Germanies built the first modern car production plant in China in 1985: Santana which again bring Chinese car industry from 1940s into 1980s world.
It was Hongkong teach Chinese to produce modern consumer products and cloths with modern standard.
