This article is biased and The Beijinger should not allow it. It favors one service provider or vender. It leads to the question of why these are being promoted and not others, and if the author and/or the publication is being paid for featuring it.
Paid for content/ advertising is always clearly indicated as such. This is a personal selection by our colleague Pauline. If you know of any WeChat service providers or vendors who our readers should be aware of, then please let us know- we'll check them out and include them in a future listing, if appropriate.
