What does it mean to sing every night and play with Yuanyang under Xiling Bridge?

When you say "strike at night", playing Yuanyang under Xiqiao Bridge means that people don't think about anything else, just want to strike at night, just like Yuanyang playing with each other under Xiqiao Bridge; This ostensibly means to describe people's very happy and carefree lives.

The deeper meaning may be to express that people live a drunken life and don't pay attention to their future development, saying that it is the development of the country.

What this poem expresses is that we should pay more attention to the future personal development and the future social development trend, and should not live a carefree and prepared life every day.

The above are the superficial meaning and deep meaning of the poem, and there are many meanings that can be expressed.
