The origin of the name "Tiejian Temple" in A Dream of Red Mansions

The prototype of the Iron Sword Temple in A Dream of Red Mansions should be the Qianwang Memorial Hall in Hangzhou. King Qian's Memorial, also known as Qiantang Temple, was the temple of King Qian Liu of wuyue (907-978 AD). Qian Liu (852-932), born in Lin 'an, Hangzhou, was the king of wuyue. He managed Hangzhou well in all aspects, especially building water conservancy, dredging the West Lake and building the seawall of Qiantang River. "History of Song Dynasty" records: "Qian Liu is the king of wuyue, and he is an iron fence to stop the rising tide of the river. The tide arrived before it was finished, and the king ordered it to be shot with a crossbow, and the tide receded. People who build a liter of soil will get a liter of money. Called Qiantang. " The reason why the author of A Dream of Red Mansions named Qian's throne after the Iron Threshold Temple should be the story of against the tide, the iron threshold of money.
