No. According to a query on the China Historical Information Network, traditional regular script was mainly used during the Sui Dynasty, supplemented by traditional running script and cursive script. The calligraphy of the Sui Dynasty was superior to that of the Southern and Northern Dynasties, and started from the Tang Dynasty. The calligraphy style was skillful and comprehensive, and it did not deviate from the rules. It had the splendor and beauty of the calligraphy of the Eastern Jin and Southern Dynasties, and the squareness and vigor of the calligraphy of the Northern Dynasties. Therefore, the simplified Chinese character "Lian" was not created in the Sui Dynasty. The Sui Dynasty (581 to 618) was a unified dynasty in Chinese history that inherited the Southern and Northern Dynasties and initiated the Tang Dynasty. It lasted for thirty-seven years.
