Origin
The character 開 combines two visual ideas to express "open." The left part, 門, depicts a gate or door — something that can be opened or closed. The right part, 开, shows something being split or separated. Together, these convey the action of opening a gate or door by pulling its two sides apart. Over time, the meaning expanded from the literal act of opening a door to the broader sense of unfolding or unsealing anything.
