both dramas about chinese culture. very interesting to learn about the perserverance of chinese culture

BY is based on university life while LU is based on high school.

Both encompasses a touch of romance (not too little but not too much) (although the romance in both are slow-paced, it is not a deal breaker but instead sheds a more accurate representation of real life)

Both can be considered as coming-of-age dramas

BY is focused on 4 female roommates while LU is 3 guys 2 girls who grew up together

Both dramas have no boring episodes and are very refreshing
