Have you ever dreamed about sending a letter to yourself or your friends in the future ? While express mail representing efficiency and speed is prevalent(盛行的)in China , there is another type of mail appearing as a new business : “ Future Mail ” . “ Future Mail ” service can make people slow down and let them understand the meaning of “ time ” in another way .
