hay fever 花粉症;
How do you know when spring is here? The prettiest signs of spring are the flowers. The plum blossoms open early, in February, but you can still find them blooming here and there in the middle of March. Another sign of spring is the farewell party. This is the time when people leave their company or move to a different office. Their co-workers have a farewell party to say goodbye to them. There is one sign of spring that nobody likes. It is called “hay fever.” Many people are allergic to cedars and start to sneeze. Their eyes water, and they often feel sleepy or have headaches.
