40.202

至𰆓（辛一反正膝字也說文云膝脛頭節也從卪桼聲或從肉作膝）。

Reaching the knees (至𰆓; the second character has the fanqie 辛 + 一; it is the correct character for 'knee' [膝]. The Shuowen jiezi states: 'The joint at the top of the shin.' It is formed with the 'joint' radical [卪] and takes qī [桼] as its phonetic element; it is also written with the 'flesh' radical [肉] as 膝).
