Even my favorite dramas normally only get up to 9.0 or 9.5 so that's considered really high, just an FYI.
It's beautiful, healing, and delightful. The characters are complex but even ones you may not initially like (such as initially-stern Aunty Feng who later smiles to light up a room, surly old Grandpa Yang who eventually comes around even if still surly), you'll grow to love. My favorites are the children and Granny Xie ("A'Nai" as A'Yao and Hongdou call her). I won't go on and on about everything I liked since many other reviews already covered it.

I also have a special place in my heart for this because the grannies and aunties remind me of my family and family's friends (as you know, in Chinese and other cultures, you address your elders as grandpa/grandma/uncle/auntie even if they're not blood-related). They touched me in ways that other cdramas modern and costume have not; though it's a slow drama, it's because all characters are fleshed out to feel real.

Minus half a point mainly because:
1. A bit draggy, but mainly on storylines about supporting characters I wasn't as invested in like Mr. Ma (the guy who is always meditating in the beginning) and the musician's romance.
2. The English songs used are annoying. Why do modern C-dramas always use English songs?? The non-English songs are good, though I wish they used some of them more (like "Hao Hao De" by Sa Ji was only used like twice despite how good it is, while they used other songs a bit too much).

These are just nitpicks though, which is why I only took off half a point.
