My boyfriend told me that plum blossoms have fallen all over Nanshan. It means that when I see plum blossoms falling all over Nanshan, I think of who will pity the flowers when they bloom. This brings about the sad emotion, and I think of the sad things that I regretted in my life. The poem "In the Mirror" from Zhang Zao uses the mirror as a line. In the three parts of the poem, five seemingly unrelated mirror images are presented, which also makes the central meaning of the poem erratic.

However, the poet's exquisite design of language and words in the poem makes these five mirror images and poetic meaning natural and appropriate. The beauty of the poem itself, as well as the hint of sadness, make people stop to think deeply and be amazed.

The history of plum science

Plum is a unique traditional flower and fruit in China, with a history of more than 3,000 years. "The Book of Songs" says: "If you want to make a soup, you can only use salted plums." The Book of Rites records: "Peach, plum, and egg salt." "The Book of Songs·Zhou Nan" says: "There are plums in the soup, but they are actually seven!" Plum blossoms are also mentioned in poems such as "Qin Feng·Zhongnan", "Chen Tomb Gate", and "Cao Feng·Corvette".

The records in the above-mentioned ancient books indicate that in ancient times, plums were used as condiments instead of cheese and were indispensable for sacrifices, cooking and gifts. At least 2,500 years ago in the Spring and Autumn Period, wild plums began to be introduced and domesticated to become domestic plums - fruit plums. In 1975, Chinese archaeologists discovered plum cores in a Shang Dynasty bronze tripod at Yin Ruins in Anyang, which showed that plums had been used as food as early as 3,200 years ago.
