"For example, in developed countries like Japan or England, their culture discourages using mobile phones for trivial matters that waste time," Kang Dim explains.

"In contrast, in our society, we spend the whole day glued to our phones, even for trivial matters. We should start using our advanced smartphones wisely for beneficial purposes, such as acquiring knowledge," Kang Dim advises. (*)
