There are actual young 2nd or 3rd gen Chinese I know in Germany who wish to migrate back to China, due to better job prospects, better future in general but their parents are often reluctant and swallowed the "SeePeePeeSee Bad" by german MSM Tagesschau, etc. but most likely those parents are aware thatt they prob don't get chinese pension since they payed into the german system and never into the chinese one. And not all are financially secure enough to miss out on the german pension (even if it is little)
One major problem is the growing inevitable divide between the diaspora and Mainland Chinese. The diaspora basically is a time capsule from the time they left China and behave as such. It's a different story if they have frequent business or holidays in China but I know many who never went to China even for holiday after going to Germany. The Children nowadys don't even garanteed to speak fluent mandarin because of suboptimal teaching, mainly from the parent but that does not make you fluent in writing most of time.
The children of course are far more reluctant to relocate back when facing active opposition from their elders.
On the other side there are those families that are sooooo cucked and fully embrace western libtard democrazy with all its colours.
Those ones are lost anyways, basically like the group of jews that were pro Hitler.
