A sunflower overwhelms Haitang.

It should be "a pear flower presses Haitang".

It means: tease an elderly husband to marry a young wife. "A pear covered with a begonia" is a folk story that has been widely circulated in the note novels of the Ming Dynasty. At present, the earliest version found comes from the collection outside Yaoshan Hall written by Jiang Yikui in Ming Dynasty.

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.
