Why are New Year's Day and Spring Festival Arbor Day important?

Because they are all legal traditional festivals.

The beginning of the Lunar New Year in China is called the Spring Festival, which is the most solemn traditional festival of China people and also symbolizes unity, prosperity and new hope for the future. According to records, people in China have been celebrating the Spring Festival for more than 4,000 years. There are many theories about the origin of the Spring Festival, but one widely accepted by the public is that the Spring Festival began in Yu Shun.

The Arbor Festival in China was initiated by forest scientists such as Ling Daoyang, Han An and Joseph Bailie in 19 15, and the time was originally set in Tomb-Sweeping Day every year. 1928, the National Government changed Arbor Day to March 12 to commemorate the third anniversary of Sun Yat-sen's death. During the period of 1979 after the founding of New China, at the suggestion of Deng Xiaoping, the 6th meeting of the 5th the National People's Congress Standing Committee (NPCSC) decided to designate 12 as China Arbor Day every year.

In ancient China, there was a tradition of inserting willows and planting trees in Tomb-Sweeping Day. The earliest roadside tree planting in history was initiated by a man named Wei Xiaokuan in Shaanxi more than 400 years ago.
