What's the difference between not having a Chinese character and not having a Chinese character?
None of the eight characters has the same extended meaning as none of the ten paintings, indicating that things are far from successful. If we want to say the difference between the two, literally speaking, the eight characters are two paintings, and there is no half without a glance, which means that things are not half done. Obviously, none of the ten paintings is less than one tenth, and the latter is farther from success. But generally speaking, people don't make this comparison, so it's a personal habit.
