Affixed

affixed, attach, refer to, append

Mnemonic

In the village, every new law must adhere to the great stone wall at its center. The elders smear thick pine resin on parchment and press it firmly against the rock until it sticks. Once the decree is affixed, no wind or rain can peel it away—it belongs to the village now.
Additional thoughts
Picture a stone wall coated in sticky resin at the heart of a village. Laws physically adhere to it, becoming permanently affixed. The wall is the village's living memory.
Quick recall
Decrees adhere to the village stone wall once affixed with resin.

Details

The keyword for 附 is affixed. This kanji conveys the idea of attaching, appending, or being joined to something else. It suggests the act of adding or sticking something onto a main body, much like an appendix is affixed to a document or a supplement is attached to a primary text. The character carries a sense of proximity and adherence, implying something that accompanies or is annexed to another thing rather than standing independently.
