In OTL, the third Chinese domination of Vietnam ended in the 900s in the years between the Tang Dynasty and Song Dynasty
In OTL, there would not be another Chinese domination of Vietnam until 500 years later under the Ming Dynasty.
What if instead, the third domination didn't end and the Song Dynasty inherited Vietnam and held it for its dynastic life, or what if the earliest Song reclaimed Vietnam and held it.
What could enable this to happen, and what would be the consequences post-Song dynasty? If there are Mongols, are they likely to inherit Vietnam?
