The word "打成" is formed by combining the character "打" (dǎ), meaning to hit or strike, with "成" (chéng), meaning to become or to achieve. Together, they create a verb phrase where "打" denotes the action of beating, and "成" indicates the resulting state, so "打成" literally expresses causing something to become a certain condition through hitting, as in "打成平手" (to beat into a tie).
