How many versions of Caigen Tan are there?

There are two official versions-Qing engraving and Qing engraving. It is recorded in "The Micro-Engraving Atlas of Huaichan" that Huaichan, also known as the owner of Linglong Temple, is unknown, regardless of whether Wenda is alive. More than twenty years ago, he wrote "Zen-minded old man" in his calligraphy works, which smacked of joking with the world. "Huaichan Iron Pen" micro-carving calligraphy has reached the realm. Carved three or five thousand words an inch square, regardless of cursive script, it is still difficult to reach the statutes after amplification, but it is a calligraphy work. Now I want to buy vegetable root tan, most of which are collected by later generations and commented, but all of them are based on the original text, so it is better to buy the original text.
