Until the Han Dynasty, weaving bamboo slips into books formed an axis of Chinese writing culture. Even in the case of wooden documents, there were cases where several strips were tied together by strings. As an example in which individual strips contained their own information and were intended to be tied together, MD14 of Han wooden slips from Juyan district are noted. They were identified as part of a single table written in columns with each other based on wooden slip 286.1.
The way of writing in columns with other than individual wooden strips was also found in the ancient Korean Peninsula, but some acculturation has been made. Wooden document No.2 excavated from the moat of Wolseong palace in Gyeongju has similar margins at the top of all four sides. Four-sided wooden doucument Gaya1602 from the Seong- sansanseong Fortress in Haman also has the same large space at the top of two sides where the letters remain well. The lines that were conscious of when writing must be found outside the document. Gaya1602 would have been made with the intention of being tied together as a sum of several wooden documents containing individual information.
However, a multi-sided wooden document is intended to be read on each side while rotating, and cannot be secured by stringing top and bottom. Gaya2645, which is also thought to be tied together with other wooden documents, has a groove for string only at the bottom. The broken upper end of Gaya1602 could be originally a groove to tie the string too. It is assumed that these multi-sided wooden documents were linked by binding only one end.
These cases contradict the assumption that the method of binding wooden documents would not have flowed into ancient Korea. The existing hypothesis that the multi-sided wooden document would have been used alone also rejected. The binding of the multi-sided wooden documents is an example of cultural exchange and transformation that took place on the ancient Korean Peninsula which was a Contact Zone.
