The confusion between zheng(徵)and wei(微)and their allographs
In literature produced before the Warring States,the written forms of zheng(徵)and wei(微)were distinguished from each other which left no possibilities for confusion.Since the Qin and Han dynasties,especially after the appearance of variants related to wei((徽)),a written variant of wei(微),the two characters began to be confused which is frequently attested in unearthed documents and extant historical literature.The differentiation between zheng and wei should take various factors into consideration,including context,grammar and phonetics.
