At first I saw this thread yest, I thought it was about a math trick or something like that la, you know, like what color is the dress some sort like that.

So I didn't click in.

But after that today, the thread still got wor, summore so many pages liao.

In my heart I was thinking, walao what kind of math trick is this, until k/ can discuss until so long one.

So I cannot tahan myself liao, so I clicked in the thread and read the beginning post.

Indeed, it was a math trick after all.
