There's a book specifically discussing this phenomenon, sadly it's only in Chinese: The Country of 'Giant Babies': A Domestic Psychologist Examining the Chinese National Character
The book talks about how Chinese people simply did not evolve emotionally so they stayed as a "baby," which means they are fully narcissistic, paranoid and co-dependent. They cannot accept failure, therefore it is necessary for them to find someone else to blame. There's one quote from the author which I find quite interesting:
How can you become a mature individual in China? Existentialism told us that I choose, I am free, and I exist. We need to be genuine, alive individuals, and make choices for our own lives. But in our country, we were told to be obedient.
Chinese culture is built on Xiao, or filial piety, which basically means to treat your parents with care and obedience. This concept exist almost nowhere else, but in China, this kind of forced obedience is almost morbid to a point where you have an entire country full of people with psychological development issues. Obey to your parents, your teachers, and most importantly, to the CCP. When you were told to obey, you were ignoring your own needs. That's why Chinese people can never develop to an emotional mature state.
And it is the reason why this sub exists.

>described Chinese culture as a "bottle of sauce - it's all stuck at the bottom, hard to move and if you put anything new into it it just gets dissolved
That would be the late Taiwanese historian Bo Yang, one of the first authors in the Chinese-speaking world to actually publish a self-reflective essay on the Chinese race, The Uglyman Chinaman.
Sadly to this day, his words falls on deaf ears to most who buy the PRC's crap.
