The family of the both drama faced demise only the both main character remain and They finally got justice in the end.
You can see how they can overcome their misery.
They're both historical
The differrence is that in dong yi the MC is female and related to concubines and in horse doctor is a male and related to medical.

- They're both connected of fighthing evil spirits though in wu xin theres no collecting points to become a deity

they're both searching for a lost tomb that have a mysterious meteorite even though the "The Mystic Nine" drama doesn't involve time travel genre..

- both are historical drama that involve medical genre that surgery is the only option though they're different plot coz Time Slip Dr. Jin has a time travel genre and Horse Doctor male lead is from the noble... some kind of status and faced some difficulties... and there's no time travel genre
- both are interesting to watch especially those who likes medical dramas

both drama are in love triangle theme.
the girl is in trouble who to choose, and she decided to date the 2 guy.. then she realize who she loves most.
they're both familiar though Flower Boy Ramen Shop is full of men than Jealousy Incarnate and their type of work are different

both have time travel genre, there's also a diary involve that owned by main lead actress of this two drama, the difference the way they time travel is that in Faith a doctor is being forced by someone to time travel while in Thousand Years of Love a princess who wants to die, time travel instead. they also have bitter sweet ending

- both have a smart female lead
- both male lead are prince who became king
- both male lead in this dramas, only love one person (stick to one)

- both main male lead of this dramas have some misunderstanding with their superior
- both dramas are focus on surgery, even though Doctor Stranger doesn't have a disaster theme
- both main male lead just want to treat the patients fairly

even though I remember you doesn't have supernatural/wuxia kind of genre, i like the feeling of brotherly love of the main male lead to their brother of this both drama.
