The same issues in the US with regards to Chinese policy exist in the Chinese view of the US as well.
Most policymakers and staffers on either side of the Pacific haven't actually spent extended time or intercultural experience with the other, and those who have the experience with both Asia and the US remained in the private sector due to better prospects and (in the Chinese case) inability to join the civil service due to age and examination restrictions and (in the US case) due to clearance restrictions.
On top of that, those in the policymaking level are those who had around 20-30 YoE within their country's civil service, meaning most policymakers and senior staffers today started their careers in the late 80s/early 90s.
This is a major reason why Chinese policymakers have been fairly hawkish compared to a decade ago, as the early 1990s was an existential decade for China - the Tiannamen Square Massacre and subsequent sanctions, the Taiwan Straits Crisis, and the bombing of the Chinese Embassy in Belgrade all solidified an anti-American viewpoint among Chinese policymakers who started their careers in that era, unlike the policymakers from 1973 to early 90s who had experience working closely with the US (eg. there was even a US Army listening post in Turpan staffed by both US and PLA soldiers during the 70s and 80s [0]).
