It’s not a typo. It is the building title of the old Tsinghua 科å¦é¦† – on the west wing-side of the å¤§ç¤¼å ‚.
You can see it is a “v” instead of “u” in the title. When I was there we used to do Physics experiments in that building. I was very curious about the spelling and too shy to ask the English teacher – what if he doesn’t know about it. I was also a bit embarrassed to advertise this to the people outside the University – what if it is a typo.
Anyway, the typo theory doesn’t hold well because I know this group of buildings are the original Tsinhua buildings designed by the Americans. If you don’t know already, Tsinghua was “donated” by the Americans using our (Qing empire) money. The empire had done too many of those embarrasing things in the early 1900 that the last emperor was over-thrown the year Tsinghua was built.
It was until after I left school, about 8 years ago that I finally solved this little puzzle. I start to see “v” used much more often in ancient English and suddenly realized that “w” was pronouced as “double-you” instead of “double-vee”. It’s all clear, “v” was the “u” in the old days, there wasn’t the letter “u” even less than 200 years ago.
