老师Emily，给我们的课代表上课， 示范正确的姿势poster。 初学者常见问题如：驼背，手心塌陷，手腕塌陷，手指无力，坐得太近或太远等。养成好的姿势须循序渐进，短则几个月，长则上年，不可操之过急。培养好的习惯。
Teacher Emily gave a lesson to our class representatives, demonstrating the correct posture poster. Common problems for beginners include: hunchback, collapsed palms, collapsed wrists, weak fingers, sitting too close or too far away, etc. Developing a good posture must be gradual, from a few months to a year, and don’t rush it. Develop good habits.
