Research on the coding sequence of GB 2312

Problem description ： I wrote in my last blog , Use gbk code , Sort Chinese fields in the database , Find homophonic words , Adjacent to the position of the code table . I guess there should be some rule , Fumbled for an afternoon , Some detours , Try to judge with partial radicals 、 The structure of words （ The upper and lower structures are larger than the left and right structures ...）、 The number of strokes of a word （ Those with many strokes are in front ）, It doesn't make sense . Finally, it came out , Now share with you .

stay GB 2312 Look for a few words with the same Pinyin in the code table

Watch them , Find the rules , Is in accordance with the pinyin and tone Sort two dimensions

Look again , answer (dá) Ranked in the generation (dài) In front of , Add another dimension , Initials and finals

Come back , Same pronunciation dài Seven words of   wear belt Almost generation loan bag stay Arrest Why is their order like this ？ Ask yourself , I vaguely remember the Winter Olympics , The order of appearance , It doesn't seem to be sorted according to the Pinyin or English of country names , I've heard of a method called stroke order sorting , I don't know how to operate .

C Search blog on the website , It's all about code tables , Copy of the , It's not what I want at all . Then I thought it was GB The beginning is the national standard , Just search the website that publishes National Standards , After many twists and turns , There is no need to elaborate on the specific process , Are tears , I finally found it .

Writing the first 3 The pen is vertical （ Smaller than horizontal ） therefore wear It's in line belt front .

The same method compares loan and bag

• loan —— Turn vertically and horizontally vertical Fold and skim
