The first pronunciation of this radical is "Chuan".
I read Yong for the first time in the next city.
Tan, a Chinese character, was the same as "harmony" (meaning harmony) and "crowding" (meaning crowding) in ancient times. Now it is the abbreviation of Nanning, Guangxi Zhuang Autonomous Region, and also the place name of ancient Tanzhou (that is, southern Guangxi, equivalent to today's Nanning and Yongning, Wuming and Longan).
