The Lô river seat above the delta, the collecting point for iron, copper and forest goods coming out of the northern hills (board).
The name Tuyên Quang for this district may be later than the Ly: the Ly-period unit we can name is Vị Long châu, up the Gâm. We could not date the name.

Places of note
- Tuyen Quang: The place
Where the sources disagree
- The campaign board entry uses the name Tuyen Quang for the Ly period; we could not date the name and the only Ly-period chau we can name there is Vi Long.
Evidence: The campaign board entry note and a modern coordinate; nothing in our sources dates the place to 1200.
"The campaign board" is OMNIA's working map. These notes record where its earlier claims were checked against the sources.
