𡼡習（上訓憚反考聲云熏熱也說文云火氣也從黑從中作𡼡今俗作熏行用已久難改亦作煄）。

𡼡習 (The first is xùn plus dàn [xūn]; the Kaosheng says it means smoky heat; the Shuowen says it is smoke and heat from fire; it is composed of 黑 'black' with 中 inside, written as 𡼡; current popular script writes 熏, which has been used so long that it is hard to alter; also written 煄).
