Zhang Tie indeed had heard about some wedding customs in some regions of Taixia Country. In some regions, when a son-in-law proposed marriage in the female's house, the female's family members would find him troubles. Take these knights from Lord Guangnan's Mansion as an instance, although they were blocking Zhang Tie's door, they were never malicious. They might have long heard about Zhang Tie and couldn't help but "test" Zhang Tie's ability out of curiosity.
The knights of Lord Guangnan's Mansion had already treated Zhang Tie as their brother's son-in-law, which made Bai Suxian happy and a bit coy. However, when these guys wanted to make Zhang Tie embarrassed, Bai Suxian became a bit unhappy as she was worried that Zhang Tie would be infuriated. Therefore, she could only throw a glance at Zhang Tie carefully.
