Today, I noticed that at the bottom of 163's news section, "Google Ads" have started to be displayed. From the embedded JavaScript code, we can see 163's Google Ad client number: `google_ad_client = 'ca-netease_js';`. The ad display code appears to be customized by Google engineers for 163, because defining single-letter variables like `var s = ''; var i;` is a common trick used by Google programmers. The line `var sfield = ' site:biz.163.com';` seems more likely to reflect the coding style of NetEase's (163's) own programming team.
I've always had a good impression of 163, and now both Google and 163 probably have reasons to smile.
