Note: the story is referring to Permanent Residency permits (aka a Chinese "green card'), not the normal residency permits that are issued to most ... and the grand total last year was 1,202 permanent residence permits issued (still a drop in the bucket compared to the estimated 200,000 or more estimated foreign residents of Beijing (though the article states that the number of foreign residents is 118,000 -- seems low to me).
But I'd be curious to know who among the foreign population would like to become Permanent Resident anyhow?
