Cherry blossoms are native to China. According to the Cherry Blossom Mirror, Japanese cherry blossoms first came from the Himalayas in China. The spread of cherry blossoms is as radioactive as all living things. Yunnan, close to the Himalayan region, is one of the earliest beneficiary areas. Therefore, Yunnan cherry blossoms have been famous all over the world since ancient times. This leads to another Japanese legend that the ancestors of Japanese cherry blossoms were brought back from Yunnan by monks, just as some Japanese insist that their ancestors are Yunnan Bai people. However, cherry blossoms spread from the Himalayas to Japan, which is more credible. "Sakura Dajian" also said that after Himalayan cherry blossoms were introduced to Japan, with careful cultivation, Japan's varieties continued to increase and became a rich cherry blossom family. After becoming the national flower of Japan, it has been nurtured and cultivated, and there are more ornamental varieties. However, some cherry blossoms originated in Himalaya still grow in Japan, such as Joe and Fei. Yunnan cherry blossoms and Japanese cherry blossoms belong to the same genus. It is a variety evolved from the original bitter cherry in Tengchong and Longling. Flowers change from single to double, and the color changes from light pink to dark pink. This color is the difference from the highly appreciated Japanese cherry blossoms. The flowers of Japanese cherry blossoms are mostly pale pink. As for the common article that the cherry blossoms in China come from Japan, this is actually a mistake. This is also related to the fact that the name Sakura is not recorded much in China classics. Because the shapes of cherry blossoms and cherries are very similar, the ancient descriptions are rather vague, and the ancient cherry blossoms are not as well known as other famous flowers, but they can still be found in ancient books. Bai Juyi's poem "A new cherry tree is planted in a small garden, so you can swim around the flowers" describes the scene of cherry blossoms in full bloom. Cherry blossoms are mentioned in Yu Ruoying's poems in the Ming Dynasty: "The rain is thin in March, and cherry blossoms are suspected of apricot blossoms." However, Japanese cherry blossom cultivation is particularly prosperous, and its reputation has overshadowed that of China, so it gave rise to the original illusion. This reminds people of a digression. China is a big country in horticulture and flowers. Today, more than 85% of the flowers in the world are native to China. Peony, Rhododendron, Peony and Rose, which are known as the top ten famous flowers in China, have been registered as "international identities" by other countries, so that new varieties in China need to be certified by them first. The only one not registered is osmanthus fragrans. At the moment I put pen to paper, it's hard to say whether I was squatted. The connection with "Sakurahara Japan Theory" makes people think that we should strengthen our research and understanding in this field.
