Group’s debut single, “Under My Skin,” lands at No. 39 on US Mediabase chart — a first for a Chinese girl group

A20 May, a new Chinese girl group launched by SM Entertainment founder Lee Soo-man, is quickly gaining global traction, breaking into music charts in both China and the US ahead of its scheduled performance at the 102.7 KIIS FM Wango Tango festival Sunday.
