To speak of more than ten years ago, at the age of only 8 to 9, I was a very naughty little boy. I often got a beating from my parents, and could be said to have a body as tough as copper and iron. So back then I was fearless, getting up to all sorts of mischief like stealing eggs, climbing high walls, stealing watermelons, picking lychees and so on! As the saying goes, if you walk in the dark for too long, you will eventually meet a ghost. This saying indeed came true for me.
