Therefore, the custom of making friends has become an important custom for all “lien anh” and “lien chi” in Tho Ha. If you don’t make friends and sing together, it’s only called “singing in pranks”. Therefore, a mandatory requirement for each Quan Ho group is to befriend at least one other Quan Ho group.
