How to remember the four English words "East, West, North and South"?

Just like the East and the West. They all end with "st", just remember that the western word "we" means "st" and the eastern word "ear" means "R" and "st"; Both South and North end with "th", and the English pronunciations of South and North are very similar. Remember that the "sou" in the south is few and the "th" is added, and the "nor" in the north can only be memorized and added with the "th". I remember when I was a child, the geography teacher asked us to recite =-=, but I thought the effect was good.
