Rather clean for a provincial capital in terms of its environmental pollution and air quality.
Your kidding us, right?

Jinan, clean? The capital of Shandong, one of the most polluted provinces in China?

The capitals of Hebei, Shanxi and Shaanxi are dirtier than Jinan in my view. Harbin and Urumqi are dirty too. Relatively speaking, Jinan ain't as polluted as quite a few of China's provincial capitals.

No doubt it was the only place San Miguel could get a job.

San Miguel has undoubtedly had other job offers recently. He has chosen the best one, I'm sure of that!
