The lotus (蓮花, lián huā, 荷花, hé huā) is known as the gentleman’s flower because it grows out from the mud, pure and unstained. The “he” in a man’s name indicates he is either a Buddhist or connected to Buddhism. The “he” in a woman’s name is a wish that she be pure and respected. 蓮 (lián) sounds similar to 聯 (lián, to bind, connect as in marriage); 戀(liàn) means to “love” while 廉 (lián) means “modesty”; 荷 (hé)sounds similar to 和 ( hé, also, one after another, uninterrupted).
