That quote is buried deep in the article, but should be emphasised for anyone travelling in a Chinese-speaking country: WeChat is easier to use than Google Translate!
It also is worth emphasising for people developing iMessage, Skype, LINE, KakaoTalk, and other platforms, who seem to want to avoid "feature creep" by denying people this kind of functionality. Users like features.
If you're interested in learning Chinese, I wrote a program to do that, but I recommend chat-based translation tools like WeChat for temporary visitors.
