Abstract:The five vulgar characters " [革卯](yi ng)" ,"[牛孛](zi )","(she ng)" ,"蛙(wa )" ,"义(yi) " in YouyangZazu are also included in the Hanzi Da Zidian and the Zhonghua Zihai. But they are not properly handled there in these two Chinese dictionaries. The phonetic notations of“[革卯]”and"[牛孛]" are not correct; as to “”, there is neither pronuncialion nor meaning in the entry; under the entry of"蛙" , its usage as "蝰(ku i )" is not included; when it comes to "SL", it lacks the usage as "叉(ch a )".
