People celebrate different days in the world. Do you know there is a World Toilet（厕所）Day on Nov.19th? Why do we celebrate it? Because toilets are very important in our lives. Even today, 3.6 billion（十亿）people in the world still do not have safe toilets, the U.N. said. The Chinese government（政府）started a "toilet revolution（革命）"in 2015. It planned to spend（花费）more money building toilets or making toilets better. Do you find there are more toilets in public places?

How long does it take you to use toilets? About three years of your life! Many people use this time to do other things. Some like to read in the bathroom. Some like to talk with friends or family on their phones there. Others like to study or work. The great poet Ouyang Xiu wrote many poems on the toilet. Is it fun?
