In May 2007, CCTV broadcast the "Longrich Cup 12th CCTV Young Singer Grand Prix" live. There was a knowledge question: Name the two cities that were the capitals of the Northern Song Dynasty and the Southern Song Dynasty. The competition judge commented: "Kaifeng Bianliang was the capital of the Northern Song Dynasty."

Kaifeng was called Bianliang in ancient times, but in the Northern Song Dynasty, there was no such name as Bianliang. This is a "popular mistake". Because the Young Singer Competition has a great influence and the teacher's comments are also very authoritative, this widely circulated mistake is corrected.

Kaifeng is actually a very old place name, but it turned out to be not Kaifeng, but Qifeng.

During the Spring and Autumn Period, Zheng Zhuanggong built a "Qifeng" city in Gucheng Village, Zhuxian Town, south of today's Kaifeng City, which means "opening up and enclosing frontiers". From now on, this place was called Qifeng. In the first year of Emperor Jing of the Western Han Dynasty (156 BC), Qifeng was changed to Kaifeng because Emperor Jing of the Han Dynasty was named Liu Qi. There was a taboo system in ancient China, that is, characters in the names of emperors and saints could not be used elsewhere, so they had to be replaced with synonyms or homophones, or one stroke less or a few more strokes should be added when writing, such as the surname Qiu. Qiu's surname was originally Qiu. Because Confucius was named Qiu, he added an ear to the surname Qiu. In order to avoid the name taboo of Liu Qi, Emperor Jing of the Han Dynasty, Kaifeng was changed to Kaifeng from then on.

"Ciyuan" "Bianliang" article: "Place name. Today's Kaifeng City, Henan Province. During the Warring States Period, it was Wei Daliang. During the Jin Dynasty, the Eastern Wei Dynasty established Liangzhou, and during the Sui and Tang Dynasties, it was changed to Bianzhou. The Five Dynasties, Liang, Jin, Han, Zhou and Northern Song Dynasties all established their capitals here. In the Northern Song Dynasty, Nanjing Road was changed to Bianliang Road in the 25th year of the Yuan Dynasty, and it was changed to Kaifeng Prefecture in the first year of Hongwu in the Ming Dynasty. "

"Cihai" "Bianliang" article: "Another name for Kaifeng Prefecture in the old days. Kaifeng was Daliang, the capital of Wei, during the Warring States Period. Later generations continued to call the place Daliang, or Liang for short. In the Tang Dynasty, Bianzhou was established here, or Bian for short. After the Jin and Yuan Dynasties, it was collectively known as Bianliang. Bianliang."

During the Song Dynasty, Kaifeng was called Kaifeng, also known as Tokyo, and also called Bianjing, but it was not called Bianliang. Kaifeng was called Bianliang in the Jin and Yuan Dynasties. It is wrong to call the capital of the Northern Song Dynasty Bianliang.
