My friend's son is getting married. Let me write him a four-screen calligraphy. Can you give me some advice on what to send?

The theme of nephew's wedding, the form of four screens, and your calligraphy style should all be considered. Hehe, this content can be very particular. I don't know whether these four screens are mounted on the wall or made into screens. What is the architectural style of the house and furniture? After comprehensive consideration, choose an ancient poem with equivalent words. Be careful not to choose works with themes such as "I would like to be ……", "Peacock flies southeast" and "Liang Zhu becomes a butterfly"! ! (Unless you insinuate that couples can't grow old together, hehe .....................)
