reposting my response to watchmaker, with off-topic first two sentences deleted. hope this version of it stays up, because i think it's a useful response:
"As far as translations changing more than once. Everyone uses a different translator on their computers (I use the translator on the safari browser), so each person will get a slightly different version. That's what makes some of this research so hard. But, while small differences exist with each translation, you'll find that the main points stay consistent."
"As far as the Weixen link. Weixin is china's wechat, and they actually do this super helpful thing where at the bottom of one article, they will suggest another article that might be of interest. i've found a lot of new stuff this way, as usually their suggestion will be the most current news item for the company. So that's what you are seeing: the old article with a link to wechat's latest suggestion at the bottom of it."
