"Ten pavilions 10" is correct in front and unmistakable in the back, but it is illegal. 1, "Soak directly in water for a long time and use it as ink" can only be used for practice, otherwise "Su Mo" is more than "Su Mo", and the written words or paintings can't be mounted because the ink has lost its gel (because it is exposed to the air for a long time during brewing), and mounting will be very obscene, that is, "displacement". Another way to "break" is to soak, otherwise it is absolutely impossible. So this move is not high.
2. I am an old man, mainly painting. Pay attention to the use of old ink in painting. The longer the better. But old ink is very valuable, so I cherish old Mo Ding, and I can't waste it at all. What about the Mo Ding root of the rest of the pencil? It's actually quite simple. When you almost can't hold your hand, switch to Mo Ding, and it's better to be the same as old and new Mo Ding, that is, all Song Yanmo or all oil smoke ink and lacquer smoke ink. You stick the remaining "Mo Ding Root" on the head of New Mo Ding with China ink (the best one newly developed in New Mo Ding), and it will be fine when it is dry. If two contact surfaces are flat, it is almost an organic whole. It doesn't matter if there is a little seam. Every time you finish writing, drop the remaining thick ink into the seam. Don't worry, a thin layer at a time, a few times, will soon be filled. It will stick fast. Keep using it!
