汉字中大部分都是形声字，顾名思义就是 行（shape）+声（sound）的字。“行”的部分表示意思，叫“义符”；“声”的部分表声音，叫“声符”。
形声字多由两部分组成：左右，上下，里外。有时左行，右声；有时右行左声。有时上行，下声；有时下行，上声。有时里行，外声；有时外行，里声。
例如：城，飘，爸，案，病，问，等等。
平时多留意一下，你会发现汉子很有趣。
As a professional Mandarin instructor with almost two decades worth of teaching experience in American schools, I came to recognize how language-learning in a school setting is only one step in the long journey of acquiring a foreign language. I felt a need and urge to bring my profession beyond school, and I believe professional teaching should be accessible to anyone at any point in their life. It is with this belief that I founded MAD Mandarin LLC in 2018 with the goal to incorporate the latest teaching methods with my own innovative approach of Mindful-Active-Dynamic to positively achieve the best language-learning results.
