长发齐腰那是贞子
[zhăng fā qí yāo nèi shì zhēn zi]
'If my long hair goes down to my waist then I am Sadako.' Sadako is a famous ghost character with long black hair from Japanese horror who became well known through 'The Ring'. In China, this netname can mean she has long hair, but also might carry a bit of creepiness or mystery like the ghost image in people's minds.
