大家好，我叫刘若愚。我出生后，妈妈把我从医院一抱回家，爸爸便说得给我起个名字。于是家里人便议论开了，有的说叫这个，有的说叫那个，但没一个能让大家都满意。这时，爸爸开口了，他说，不如叫“刘若愚”吧，“刘”是我的家姓，“若愚”取自“大智若愚”的后两字。意思是? Hello everyone, my name is Liu Ruoyu. After I was born, my mom took me home from the hospital and my father would say that gave me a name. So the family members then talk about the open, and some say this, some say that, but no one can make everyone satisfied. At this time, my father spoke, he said, it is better to call “Liu Ruoyu” it, “Liu” is my family name, “Ruoyu” taken from the “big wisdom” after the last word. meaning is?
