我妈说她女儿真好看我爸说他儿子真好看
[wŏ mā shuō tā nǚ ér zhēn hăo kàn wŏ bà shuō tā ér zi zhēn hăo kàn]
"Wo Ma Shuo Ta Nv E Zhen Hao Kan; Wo Ba Shuo Ta E Zi Zhen Hao Kan" means both 'My mother thinks her daughter looks very beautiful' and 'My father says his son is handsome'. These contrasting perspectives are put together here probably to imply self-appreciation in a humorous way.
