My father has an old yangqin, see picture, that I want to fix and learn to play on and hope that some can help. It is out of tune and has broken strings. I need to know what size string to use and where and also the tune layout.
This yangqin does not look like either model 401 or 402. It has 2 rows of ten bridges. The row on the right has 3 strings each and the row on the left has 2 strings each.
