Self.VNCup.com features Self-heritage-websites personally updated by the authors themselves—individuals who possess an IDtity.com (Examples: YourIDtity.Designer.vn, YourIDtity.UAH.Engineer.vn, YourIDtity.AI.Mtery.com...). This distinguishes them from Folk.VNCup.com, which consists of Folk-heritage-websites curated and maintained by Volunteers.
Sub-domains for Self.VNCup.com websites do not contain hyphens (-). This is to distinguish them from Sub-domains of Folk.VNCup.com, which typically include hyphens (-) (e.g., Banh-Mi.Bread.vn, Ngo-Viet-Thu.Architect.vn...).
