呵呵，我又飞来了。 The market is bustling and hustling. The market is very busy. The market is very crowded. The market is lively.

In this context "hustle and bustle" is an Idiom close, in meaning, to 热闹, but today fewer people use this idiom. More often "crowded market" or "packed market" is used ( however it does not express the market's 人气 )。

In the U.S., people still do say "bustling." As in, "The market was bustling." I think that the meaning is the same: crowded and lively.

关于“热闹”，虽然那个老朋友我是五十多年前碰到的， 我还没有找到一个合适英文词，我们必须用几个 英文词解释这个词的意思，比如 bustling with noise and excitement
