你别把我想得那么一文不值
[nĭ bié bă wŏ xiăng dé nèi me yī wén bù zhí]
The meaning is 'Don't think so poorly of me'. It implies the owner of this name believes in their own worth, and does not want others to belittle them or consider them worthless or of little value. There may be some frustration or defiance involved here.
