Here are five major types of Korean Hanja calligraphy, which are derived from Chinese calligraphy.
1. Seal scripts
Seal scripts (Korean: 전서; Hanja: 篆書; RR: jeonseo) are scripts featuring uniformity of stroke thickness and spacing of vertical, horizontal, and curved lines. It is often use for seals and chops.
2. Cursive or grass script
Cursive script (초서; 草書; choseo) is known for extreme economy in individual pen strokes. Extreme cursive script is not legible for most people because different characters may resemble each other when written in cursive script.
3. Block script
Block script (해서; 楷書; haeseo) Each block script character is roughly the same size proportion and fitted into a square space. Chinese characters are frequently written in block script.
4. Semi-cursive script
Semi-cursive script (행서; 行書; haengseo) is a practical style intermediate between block and cursive script. It is legible for most people.
5. Official script
Official script (예서; 隸書; yeseo) was developed from seal script form. It is angular in appearance and much more legible than cursive or seal script.
