What is the historical origin of cherry blossoms in China?

Cherry blossoms and cherry blossom cultivation have a long history in China, dating back to the Qin and Han Dynasties, and even spread all over private courtyards in the Tang Dynasty.

Bai Juyi wrote a poem "A new kind of red cherry tree has been planted in the yard, so it is easy to swim around the flowers". The red cherry here means that cherry and cherry are difficult to distinguish, which is not important. Indeed, there are not many records about cherry blossoms in ancient books. In the past, peach blossoms or cherries were widely planted in gardens or farmyards in the south of the Yangtze River, but there were few cherry blossoms. This may be related to the fact that two peaches can be both flowers and edible fruits. In recent years, cherry blossoms have been widely planted and appreciated in parks, campuses and private courtyards in China. Tong Yuan Park in Kunming is an early cherry blossom viewing spot. The author has read it many times. Cherry blossoms are in full bloom, full of flowers and blushing, which can surpass the shape of Peach Blossom Garden.
