Places, like people, are imperfect.

So, how do you decide where to settle down - especially in a foreign land? What cities steal the hearts of expatriates in China? And why?

These were the questions I sought to answer in a marathon of interviews with the State Administration of Foreign Experts Affairs, which is compiling the Most Attractive Chinese Cities for Foreigners list.

To this end, it has also been gathering firsthand accounts and suggestions from expatriates for its annual Amazing China campaign on a China Daily website. Voting ended on Aug 31, and the results will come out in early November.

Every year, the administration examines one or more of the cities expats often list among the country's most habitable. The administration this year focused on Guangzhou, which didn't make the top 10 last year, when Shanghai, Beijing and Shenzhen respectively topped the list. Xiamen ranked ninth and Qingdao took 10th.

But Guangzhou ranked sixth in 2011.

The campaign involves the administration of two-page surveys in which expats check boxes to evaluate various dimensions of the good, the bad and the ugly about their host cities - healthcare, pollution, entertainment options and the like.

The essential question is: Why have you stayed in the Chinese city in which you live?

Emotional attachment turns out to be more important than one might imagine.

Foreigners will leave a Chinese city with good healthcare, schools and tax policies if they don't feel a personal connection. And they'll stick around in a city they have feelings for, despite traffic jams, language barriers and overcrowding.

It's perhaps like relationships with people, in which we often learn to live with the faults of those we love.

Many have highly individual specifications.

"The most important thing expatriates judge a city by is whether you can navigate it by walking," Guangzhou Modern BRT and Sustainable Transport Institute director Karl Fjellstrom says.
