What is the best monument to learn Han bamboo slips calligraphy?

The series of Selected Calligraphy of Ancient rubbings published by Cultural Relics Publishing House made up the blank of domestic rubbings publishing in a certain period, but now many professional publishing houses have produced a large number of fine rubbings, and the series of Cultural Relics Publishing House is very poor. Some are not rare books, and some are "technically processed" and completely lose their value (such as Mount Tai Diamond Sutra). Therefore, Shanghai Painting and Calligraphy Publishing House is the first choice for buying monuments now. In addition, Henan Fine Arts Publishing House has recently published eight editions of Selected Works of Famous Inscriptions in China, Selected Works of Famous Inks in Past Dynasties by Jilin Literature and History Publishing House, and Overseas Heritage of Famous Inscriptions in China by Jilin Photography Publishing House, all of which are very good, especially the last one. The selected edition is an outstanding rare book that has not been published in China and has been lost in Japan, including four masters from Tang Kai.
