Initially the story was reasonable but as it goes on the story starts to get ridiculous with contradictions.  Episodes 21 onwards gets illogical especially when Huan Er chose her dad over husband. Imagine you chose to jump into the lion den again when knowing your dad is such a rascal and your love chemistry is so great.   Episodes 22 to 25 are just plain boring...merely to get to episode 25. Further the geography is completely ignore  as one can move from Hangzhou to the north so quickly demonstrating poor research.
