我姓邓却登不上最高的山峰
[wŏ xìng dèng què dēng bù shàng zuì gāo de shān fēng]
The meaning is 'My surname is Deng but I cannot climb to the highest mountain peak.' It conveys the irony that although the person’s surname (Deng, which phonetically resembles 'climbing') implies a metaphorical ascent, it is not realized.
