World Laughter Day was started in Mumbai, India in 1998 by Dr Madan Kataria, organizer of the worldwide Laughter Yoga activity．

The celebration of World Laughter Day is for world peace and is a plan to make good friends through laughter．Now more and more people are joining the Laughter Yoga movement．On the 9th of January, 2000, more than 10,000 people gathered in Denmark to celebrate the first World Laughter Day．It was very successful．

World Laughter Day is now celebrated on the first Sunday of May every year．Hundreds of people all over the world laugh together on that day．No one thinks that laughing doesn't make us feel good．

Today, some people in the world still face war（戰(zhàn)爭）．Laughter is a good way to deal with world problems．When different groups laugh together, they can get along better．Many difficult problems can become easier to solve if people feel good．

Laughter is a world language, which is the same in every country．We should believe that only laughter can bring the world together and help people become good friends．
