It was not until 1980s that Su Shi wrote "a pear flower hits a begonia" to mock Zhang Xian. This statement confuses folk stories with historical facts. Su Shi really got back together because of Zhang Xian's concubinage. Su Shi wrote that "Zhang Ziye still heard of buying concubines to write ancient poems at the age of eighty-five", but Zhang Xian's poems did not survive.
Extended data:
Some people on the Internet regard "A Pear Blossom Blossoms Begonia" as Su Shi's work of teasing Zhang Xi 'an to take a concubine, which is wrong. They all write poems to tease elderly husbands to get married, so in the process of circulation, elegant original poems are replaced by more popular and straightforward folk jokes, which leads many people to mistake them for truth.
"A pear flower hits a begonia" is clear at a glance: Zhang Xian, an 80-year-old man with white hair, married a girl as beautiful as a begonia flower 18 years old, so Su Shi took the opportunity to ridicule Zhang Xian's wedding night "the old cow eats the tender grass".
Therefore, the answer to "a pear flower hits a begonia" or "a pear flower hits a begonia" is easily solved: an 80-year-old man with white hair naturally has white hair. Therefore, "a pear flower hits a begonia" may be a rumor.
