Who is more important, writing brush strokes or playing guzheng?

It's all important, mainly depending on your own preferences. If you can't play the guzheng with five tones, you'd better not play it, because playing the guzheng is mainly about listening to the interval, so that you can tell whether your guzheng is accurate or not and whether you play it well. But you still need to know whether your family supports you or not. (Hope to adopt)
