The traditional Chinese characters of the cylinder are

Traditional Chinese characters refer to Chinese characters with more strokes replaced by simplified characters after simplification. The latest standard is "Standardizing the Arrangement Table of Traditional Chinese Characters and Variants", which was promulgated and implemented in the State Council on June 5, 20 13. There is no corresponding traditional Chinese characters in this table, so there is no need to simplify it. "Guan" is an inherited word, not a traditional Chinese character or a simplified Chinese character.
