求助，大侠们帮帮我啊
小弟初学汇编，刚看到一个汇编显示汉字的程序，对我非常有用，但其中汉字的字符图形表的定义不大懂（红线位置），请各位帮个忙啊！！code segment
assume cs:code,ds:code
org 100h
main proc far
start:jmp begin
;汉字:仁
ren dw 300h,0,3c0h,0c0h,33fh,0fff0h,0f00h,0,0c00h,0,3c00h,0,0cc00h,0,0c00h,0,0c00h,0,0c00h,0,0c00h,0,0c00h,0h,0cffh,0fffch,0c00h,0,0c00h,0,0,0 ;要显示的位置
row dw 50
col dw 50
off dw 36 ;每次要增加的距离
lp1num db 0
lp2num db 2
lp3num db 0 ;第3层循环的次数,最大为16
lp4num db 0
lp5num db 0
cmpnum dw 8000h
n db 1 ;设置字体大小,默认一个象素画一个点
begin:push ds
xor ax,ax
push ax
mov ax,code
mov ds,ax
;设置屏幕显示方式320*200彩色方式
