"If all you have is a hammer, everything looks like a nail."
This blog is partly devoted to the sharing of my learning of the English language (my well mastered mother tongue is Chinese and I am not an English teacher) and its *cultures*, partly to the current significant trends in Canada and in the world, and partly to my own random thoughts and little life. I am not religious, but I am somewhat interested in Christianity and Buddhism, among other personal interests. Welcome. And, have a good day.

The traditional two-week construction holidays begin today in Quebec. It's no coincidence that they largely concur with the hottest summer days.
But boy, the last day preceding them, i.e. yesterday, was excruciatingly hot. I don't know how construction workers could manage to do some work in yesterday's weather.

關於 risks 的 n 對 n 的交易,其實也是零和遊戲。例如 保險 (insurance)。
In those cases, which party is the consumer, and which one is the seller? And how to calculate the consumer surplus and the like?
