JLPT0 G13 S0 F5000

The relevant bronzeware inscription form combines 彡# (hair fully layered over the head) + a depiction of a young woman with three slender hairpins thrust deep into and commingling with her hair (compare 潛 and 妻) → *three* → *join*; *mix*; *meet* (← groups of three people commingling in coming, going or visiting ← three pins commingled in the hair) → *come*; *go*; *visit*; *obey*. As with 壱, 弐, and 拾, this character is used as a substitute for the usual number (in this case, 三) in documents as a precaution against forgery.
