I definitely agree with Du Chun's description of YM. In terms of what Du Chun said that he thinks YM needs a guy who can "control/restrain" her sounds a bit too chauvinistic for my liking. I heard him used the character "zhen zhu" meaning "to restrain/to control/to weigh down on her" in the video interview but I heard some fans said he also used the character "jia shi" meaning "to drive/navigate/direct" YM. A lot of YM's female fans, especially the Beijing ones, hate that term since they found it derogatory and full of masochism if used upon the opposite sex. Based on these comments and what tidbits I know about Du Chun, he's definitely exhibits the traits of a classic "northern Chinese man" = patriarchal. I just can't imagine YM being with a chauvinistic guy. Can you imagine fiery verbal exchanges between them? (remember the arrogant guy from Central Theater Academy in Happy Camp episode?)
Even though i don't really know what is the true nature of FengMi's relationship, but I definitely don't think YM can always have the upper hand in their teasing/bickering. The driving incident comes to mind.
P.S. I personally think Du Chun and his rumored girlfriend, Zhang Jia Ni (girl from Dream's Link) are very likely an item, even more likely than FengMi. Cuz I saw paparazzi photos of their dates in Beijing + Zhang Jia Ni keeps leaving romantic comments on Du Chun's weibo and Du Chun. LOL
