Primarily, Dong Xinxian's status was too low. For the main husband of a wealthy family, either it was for political alliance or he could manage the household. Dong Xinxian couldn't do either; his configuration clearly showed he was made to be minor, not major.
During this period, Dong Xinxian did try testing a few wealthy women who were chasing him closely. However, none wished to marry him, and he wasn't willing to be a minor husband.
But if it were Qi Gongshuangshuang, Dong Xinxian was confident in getting Qi Guanshuangshuang to marry him as her main husband.
