If the double-byte square is decomposed into nine areas, as shown below ① ② ③ ① ⑥ ② ゛ ⑦ ④ ⑤ ⑥ ③ ゜ ⑧ ﹐﹒ ④ ⑨ ⑦ ⑧ ⑨ ⑤ Two districts﹔﹕ Zone 3 or above A single byte can supplement the points in areas 1 and 3 or 7 and 9, several of which are the points closest to the corners. The points in area 46 can only be realized by moving half a byte, and the accuracy is reduced. Through lateral movement, the conversion of 1.5 phase areas can be achieved to enrich the position of the points.
