We observe an Android user figured out how to make Google Contacts sort his Chinese surnamed contacts in Hanyu Pinyin order. How to do the same thing, on desktop? Yes, I want to keep my main language choice still English, if you don't mind.
Yes, I also tried reordering my secondary language preferences in my browser, and my Google account.
Indeed, even having my browser put zh-CN in the very front of the requests it sent,
Accept-Language: zh-CN,zh;q=0.9,en-US;q=0.8,en;q=0.7,zh-TW;q=0.6
didn't help a bit.
Visiting https://contacts.google.com/?hl=zh-cn simply made the interface language zh-cn. But didn't fix the order.
Feel free to move my post to the proper Stack Exchange.
