Both shows are set in the Chinese Republican era, with very good plots and very smart male leads. Both male leads from both show also share very strong relationships with their brothers.

Both shows portray friendship between three seemingly very different people, together they solve cases and uncover some very big, ugly truths. Tang Fan is very similar to Lu Yao as being the brain of the trio and also a foodie, and also very good at making his best friend paying for stuff. The bromances in both shows are also very sweet ??
