The original pronunciation of "枨" can also be seen from the sound symbols. KangXi Dictionary - ChenZhong - wood -枨 ":" ...... "TangYun - GuYin" ZhiLiang cut, sound long." Song Ouyang Xiu's "Profile": "Jia Shu Tuan Tuan can be climbed, and the autumn fruits of the pressured branches are gradually glistening.

So what? Soil and water are different."
