Ok, so if I "baidu" Jolla, one of the first links directs me to another search results page which directs me to http://mobile.zol.com.cn/413/4130375.html.

The date is there, but in what I recognize as Japanese characters (Kanjis), unless the Chinese ones for dates are the same? I have no idea what it says though :-)

It's nice to find actual Chinese pages with information about Jolla, especially when jolla.com doesn't have a Chinese translation any more.
