One of the very important aspect of how these nib behave ad to do with its origin and its designed intent. quite obviously it was not designed for cursive or any form of Latin based language writing, and as one might expect, these nibs are all tuned and with a grind catered for writing the Chinese language which dictates that it write different and with very different flow, feedback, toothy-ness so to speak.
A lot of the complain come from this single element of customer expectation ( or rather misconception ). And also Chinese fountain pen , especially vintage models tend to require run in to the nib ( typically after a single fill of writing minimal ). End users are expected, in fact encouraged to tune for their own ( in light of fact that the Chinese language had many different Hands of writing style and execution ). Its not uncommon to see 2 identical fountain pen model from 2 different user to end up with vastly different tip profile even if they tend to write the same HAND ( cursive writing in Latin based language seldom demand such big difference ).
if one check the tipping of these older models ( and also many new one ) one would see tha the tipping generally fellow more or less a 2 bladed spring clasped together type of grind instead of a more round off grind as most European fountain pen would had and this usually put those writing in cursive in a very disadvantage if not knowing.
