The origin of Chong Er has always been controversial. One theory is that there is a stone tablet in the center pavilion of West Lake in Hangzhou, which is the "Chong Er" handwritten by Emperor Qianlong of the Qing Dynasty. The second theory is a stone carving on a cliff in Mount Tai. This stone carving is on the west side of the winding road on the north side of Wanxian Tower in Mount Tai. It was inscribed by the talented Liu Tinggui in the 25th year of Guangxu's reign in the Qing Dynasty.
To the west of the winding road on the north side of Wanxian Tower in Taishan, Shandong Province, there is a famous cliff stone carving: "Chong Er". It was inscribed in the 25th year of the reign of Emperor Guangxu of the Qing Dynasty (1899) by the talented scholar Liu Yangui. This "Chong Er" is an anagram, with the word "(风 in traditional Chinese) moon" removed, meaning "wind and moon are boundless".
In the summer of 1985, contemporary calligraphers Zhong Ling, Xie Fengsong and others held a calligraphy and painting exhibition in Huiyang, Guangdong. During the period, they went to Xunyan Beach in Daya Bay for a trip. Facing the boundless wind and moon, Zhong Ling from Shandong made his debut with the Taishan stone carving "Chong Er". In this sentence, Xie Fengsong responded with "Nianhua": Chong Er; Nianhua.
Xie Fengsong’s couplet is framed by the word "年华": [年华], which means "time is limited", has a very profound meaning. This couplet was carved on a stone on the Xunyan beach in Daya Bay and soon spread throughout the country. The couplets are unique throughout the ages. The upper and lower couplets are both word riddles, but what really constitutes the absolute is not the riddle, but the answer: Time is limited, love and moon are boundless
