Introduction to the Zhenghong Gate: The Zhenghong Gate is a three-coupled hard-mountain-style building with a glazed roof and six opposite vermilion-lacquered fence-style doors, retaining the characteristics of the Manchu ancestors who used wood as a fence. Zhenghongmen looks simple, but it fully embodies the Qing Dynasty emperors and later generations' excellent thoughts of not forgetting the hardships of their ancestors' entrepreneurship and preserving their ancestral heritage. The title of the poem "Xingjing Mausoleum" by Emperor Kangxi, the ancestor of the Qing Dynasty, said: "Looking at the mausoleum to pay homage, meditating on the great undertaking." When Emperor Qianlong visited Yiling for the second time and inspected the ancient city of Xingjing, he once wrote in a poem: "How difficult it is to start a business with no tears, and thousands of households in nine layers cannot find a safe place." It is the outstanding traditional ideological virtue of the Chinese nation that future generations should not forget the hardships faced by their forefathers in starting a business, and encourage future generations to work hard, defend the motherland, and create a better future. It is fully reflected here.
