Organizational relationship is generally based on the letter of introduction of organizational relationship transfer. If you really don't know where your organizational relationship is, or you can't find the relevant receipt of the letter of introduction of organizational relationship transfer, your party member file can still prove your party member identity. Let your current work unit or the community where your account is located receive your file and establish a relationship with you.
