“双弧式桥马筝”是我自一九七九年开始经过反复实践而设计出来的.这张筝与一般筝所不同的是:1.底板同面板一样呈弧形.2.在琴腔的横切面上,面板至底板的距离是高音部分最短、低音部分最长(见图1). The double arc bridge horse zheng was designed by me after repeated practice since 1979. The difference between this kite and the general zheng is: 1. The bottom plate is arc like the panel. In the piano chamber cross-section, the panel to the floor distance is the shortest treble part, bass part of the longest (see Figure 1).
