When is Arbor Day in China?

March 12 is Arbor Day in China every year.

In ancient China, Arbor Day was not clearly defined by law, but our people have always attached importance to afforestation. There is a cloud in the Book of Rites: "The moon of Meng Chun is full of virtue." As early as the Five Emperors BC, Shun set up Guan Yu, one of the "nine officials", to handle the forestry affairs of the whole country.

Tomb-Sweeping Day was an important time for China to plant trees in ancient times. Before and after Tomb-Sweeping Day, the spring was bright and the spring rain was falling, and the survival rate of planted seedlings was high and the growth was fast. Therefore, China has the custom of planting trees in Qingming since ancient times.

19811February 13, the Fourth Session of the Fifth National People's Congress deliberated and adopted a resolution on launching a nationwide voluntary tree planting campaign.

In cities, street trees can also make beneficial contributions to human society. A tree can store the pollutants emitted by a car driving for one year 16 km. Many trees can absorb harmful gases, such as 1 hectare Cryptomeria fortunei forest, and can absorb 60 kilograms of sulfur dioxide every day. Others, such as Ailanthus altissima, oleander, Ginkgo biloba, Sycamore, etc., all have the function of absorbing sulfur dioxide.
