Bank Holiday

Today morning teacher told us next Monday is Bank Holiday but I am very confusing with it. I am a foreigner and this time is my first time been to England so I can understand it, then I surfing the internet find out the answer. Oh it turns out that in that day we can not go to school, even all of company. I remember this week is International Labor Day, in China all of people can not work, what is different between Bank holiday and International Labor Day, may be they are same but may be they are dissimilar, although I have 3 days with this holiday but I can't lax, I should make a plan for Bank holiday. everyone join Bank holiday, move you body.
