Are bamboo slips still used in Tang Dynasty?

Bamboo slips have been used for a long time in the history of China. It is said that bamboo slips originated in the Western Zhou Dynasty. Bamboo slips recorded in history are from the pre-Qin Dynasty to the Western Han Dynasty. During the Western Han Dynasty, paper was widely used. As for the Five Dynasties, Ten Kingdoms, Sui and Tang Dynasties, paper has become popular. Therefore, bamboo slips in the Tang Dynasty have long since withdrawn from the historical stage.
