The word green in "The Spring Breeze Turns Green to the South Bank of the River" in Wang Anshi's "Mooring at Guazhou" in the Song Dynasty.
"Green" means: blowing green. Thinking of the wonderful effects produced after the spring breeze blows, the invisible spring breeze is transformed into a vivid visual image - the spring breeze blows, grass begins to grow, and the thousands of miles of river bank is covered with fresh green. This writes the spirit of the spring breeze, and the poetic thoughts are much deeper.
Creative background
In 1070 AD (the third year of Shenzong Xining), Wang Anshi was appointed Tongping Zhangshi (prime minister) and began to implement reforms. However, due to attacks by opposition forces, he was forced to resign as prime minister several times.
This poem was written in February of the eighth year of Xining (AD 1075), when Wang Anshi came to Beijing to pay homage to the prime minister for the second time.
