The three seasonings suggested are:
Ginger: Ginger can remove the fishy smell of ribs.
Star anise: including star anise, cinnamon and fragrant leaves.
Salt: Salt is an important condiment.
The three seasonings that are not recommended are:
Cooking wine: Cooking wine can remove fishy smell and leave a strange smell.
Vinegar: Vinegar is not suitable for stewing with ribs.
Thirteen incense: Thirteen incense masks the fragrance of the ribs themselves.
Personally, I suggest stewing ribs three times.
