Is the pencil for drawing better, Chinese or Kyle?

China, because until the end of 18, only Britain and Germany had pencils in the world. Britain and Germany cut off the supply of pencils to France after Napoleon launched a war against neighboring countries. Therefore, Napoleon ordered the French chemist Comte to look for graphite ore in his own country and then make pencils. However, the quality of French graphite ore is poor and its reserves are small. Comte mixed clay with graphite and put it in a kiln for barbecue to make the most durable pencil lead in the world at that time. Pencil lead produced by different clay proportions in graphite has different hardness and color. "H" is the initials of the English word "Hard", which stands for clay and the hardness of pencil lead. The larger the number before "h" (such as 6H), the harder the pencil lead, that is, the greater the proportion of clay mixed with graphite in the refill, the less obvious the written words, which is often used for copying. "B" is the initials of the English word "Black", which stands for graphite and is used to indicate the softness of pencil lead and the obvious degree of writing. With "6B" as the softest and blackest handwriting, it is often used in painting. The label of ordinary pencils is generally "HB", and the label of pencils used to paint answer sheets in exams is generally "2B".
