I was actually thinking myself that there were a lot of parallelisms.
1. There are the four commanders (4 heavenly kings) the protagonist faces (post #3073246) on the path to face the antagonist 2. One of the ultimate fights is younger sister (protagonist - post #3051058) versus older sister (antagonist - post #3073234) 3. The big bad is both the protagonist's and antagonist's mother (post #3073255) that is also the head of their family 4. The older sister is allied with the mother for most/all of the story 5. The younger sister was abandoned/almost disowned by the mother for apparently being deficient 6. The younger sister recruits/befriends a crazy cast of characters that helps her with her challenges 7. The younger sister wins the open respect of the 4 heavenly kings 8. It is not the older sister that ultimately wins the day but the younger sister, despite the apparent differences in strength
It almost should be in the pool "About Time - Saw It Coming" (pool #4661).
