【activity】Arbor Day

- Mar 12, 2018 -

The Arbor Day is a festival that promotes and protects trees in accordance with the law and mobilizes the people to participate in the festival of planting trees. According to the length of time, it can be divided into tree planting day, planting tree week, and tree planting month, which are collectively known as International Tree Planting Day. It is advocated to stimulate people’s enthusiasm for loving forests and afforestation through such activities.

The Arbor Day in China was established by forest experts Han An and Ling Daoyang. It was initially determined on April 5th Ching Ming Festival. In 1928, in order to commemorate the third anniversary of the death of Dr. Sun Yat-sen, the tree-planting festival was changed to March 12.
