I read 2 articles in the Chinese newspaper yesterday about languages. One about doctors who can't speak/read Chinese competently and the other commented on the inconvenience caused to some passengers, especially the elderly as directional signages and station announcements in MRT are only in English.
In the first article, the author (doctor working in a hospital) was from a SAP school and he felt sad that a Chinese national TCM doctor in the hospital expressed surprised when the author could read Chinese newspaper. Although many of us could advance in our career without much in-depth knowledge of Chinese, we could become a laughing stalk when foreigners see us Chinese can't even read/speak or understand Chinese very well.
The second article mentioned that announcements and signages in Switzerland are in the 4 official languages.
