你太牵强你别勉强
[nĭ tài qiān qiáng nĭ bié miăn qiáng]
'You're forcing it, so don't push yourself' This expresses a sense where one thinks the other is being insincere or forced into something unwillingly. Perhaps implying that it’s okay to quit or not proceed if you feel forced to do something because the result would be artificial and lacking in sincerity.
