If someone asks how old you are, how would you respond with a funny smile?

You can avoid this topic humorously, or you can respond directly with the humor of "Fang Shilin Bar".

It's also impolite for brothers to ask others their age directly.

Age refers to the length of time from birth to calculation, usually expressed in years. Age is a natural sign with biological basis. After a person is born, with the passage of the sun and the moon, his age increases, which is an irresistible natural law.
