我从事声乐艺术事业已四十多年。回顾一下所接触到的学声乐的人，从当年的同学到后来的学生，学得好的和学得差的都见过不少。从中我逐渐悟出一个道理，那就是：凡卓有成效者，除了具有学习声乐所必需的条件之外，无不具有好的思想方法，这就是能全面地、辩证地用发展的观... I have been engaged in the art of vocal music for more than 40 years. Recalling the contacts learned vocal music people, from the classmates to later students, have learned well and learned poor have seen quite a few. From which I came to realize that the truth is that all those who are successful, in addition to having the necessary conditions for learning vocal music, have good ways and means of thinking that can be fully and dialectically used for development.
