I went to Google Trend site to check some statistics. When I choose Indonesia as the location search, Google Trend will give more spesific results based on subregions. I also saw: Risu, Indonesia (see picture).
OK, I’m probably not good in Geography subject. But, I never heard about a city named Risu. May be, it’s there, somewhere in Indonesia. But, I never heard of it. There is Riau.
I asked Google about Risu, Indonesia. Google does not know either and give me a suggestion: riau, indonesia.
Well, let’s see the keyboard, find where “A” and “S” are.
