Definition
一二 is a fixed expression meaning 'a few' or 'a little bit'. It is not simply the numeral 'one, two' — it is used as a noun phrase or adverb to indicate a small number or amount. You often see it after verbs like 知道 (know) or 了解 (understand) to mean 'know a little about', or on its own to mean 'a few'. For example: 我只知道一二 (I only know a little).
