ink stick

基本解释

Lin: Yes. You need writing brush, paper, ink stone and ink stick. However, we often use ink instead of ink stick now.
對。你需要有毛筆，紙，硯台，還有墨塊。但是現在我們都用墨汁，不用墨塊了。
And we pour some water into it, and we rub the ink stick, and then we can get the liquid ink we are gonna use in painting and writing.
我們往硯台中倒一些水，在它上麪磨墨，然後我們就可以得到用來寫字作畫的墨汁。
With this foundation in place, one then attends to posture: grinding the ink stick evenly, holding the brush neither too tightly nor too loosely.
然後要注意寫字的姿勢：磨墨應耑耑正正，握筆要不松不緊。
