没有娜姐的快本是不完整的
[méi yŏu nà jiĕ de kuài bĕn shì bù wán zhĕng de]
This translates as 'Without Na Sister, Fast/Quick Edition is incomplete.' This net name likely refers to a program known as 'Happy Camp' (快本 'Kuaiben' may be referring to this), a popular variety show on Hunan TV where Adi Li ('Na Jie') was an iconic and popular hostess making great contributions and holding a core role in the show. The person who adopts such a user name must like her so much that they feel that without her on the scene it loses its charm and wholeness.
