Zheng Banqiao. When Empress Dowager Cixi celebrated her 70th birthday, she asked Zheng Banqiao to inscribe the word "longevity" on her. Zheng Banqiao was already over eighty years old at the time, but he still seriously inscribed the word "Shou Yinglian" for Empress Dowager Cixi, and wrote his name and era number on the word "Shou". This longevity character is well preserved and is a precious cultural relic in the history of Chinese calligraphy.
