If you need some luck in your life, one of the most known is the four-leaf clover (苜蓿). Here's what you should know about this little green plant.
The clover is Ireland's national symbol, and most have three leaves, standing for faith (信仰), hope, and love. Because it is hard to find one with a fourth leaf, it stands for luck.
The clover plant spread from Ireland across the world, and so did the idea of a four-leaf clover as a symbol of luck. In Korea, people use them to make a lucky meal. And in Italy, car company Alfa Romeo used to paint a four-leaf clover on the side of its race cars. One of its drivers started the practice for a race in 1923, and he ended up winning the race!
Some say there's a 1 in 10, 000 chance of finding a four﹣leaf clover in the wild, but you can increase your chances. If you can find one, you 'll probably find another. Since four﹣leaf clovers tend to(倾向于) be found close together.
While four leaf clovers probably don't have special power, a little extra (额外的) luck is always nice to have. Try looking for one and see what happens. It just might be your lucky day!
