Abstract: Co-edited by Liu Fu and Li Jiarui in 1930s, Song Yuan Yi Lai Su Zi Pu is a book of folk characters collection of different historical periods.The greatest contribution of this book is its collection of multitudinous simplified Chinese folk characters, but there are also problems.Due to the editors'carelessness, they often identify the original or folk characters according to the writing habits of later generations or individuals, hence the problems with Zi Tou and Zi Xing of original characters.There are also problems with folk characters collection, such as left-out, mistaken collection, repetition, fusion of original and folk characters, showing the editors'subjective preference of simplicity to complexity and of part to whole.
