April 19, 2013 marked the fourth annual Chinese Language Day held by the UN in order to appreciate the beauty of the Chinese language and the historical importance of the culture. The celebration is held each year in April on Guyu, which translates literally to "grain rain," one of the 24 solar terms created to mark agricultural activities throughout the year. Festivities include lectures on ancient Chinese poetry, an exhibition of paintings and calligraphy, and performances of ancient songs and musical instruments.
