What do you mean, "Chang 'an is expensive, but it's not easy to live in a big place"

"Chang 'an is expensive, but it is difficult to live in a big place" is an allusion, which means that Bai Juyi went to Chang 'an before he became famous. At that time, there was a literary veteran named Gu Kuang, who said to Bai Juyi who came to visit, "Chang 'an is expensive, but it is not easy to live in a big place. "

This is Bai Juyi's name, by hand. Let him be quiet. In fact, it can also be said that the dignitaries at that time underestimated Bai Juyi who had just arrived in Chang 'an. Later, after reading Bai Juyi's famous sentence "wildfire never quite consumes them, the spring breeze blows high", Gu can't help but sigh: "It's easy to live in it."

It means that if you can write such a poem, you will not be afraid of Chang 'an being expensive, and it will be easy to live and develop in this city.
