成语
Okay, the thing is that most of the remaining C1 grammar points are quite obscure; I'm open to requests/suggestions but I feel like I for one might rather get a firmer handle on points up through B2 etc. before dwelling heavily on the C1 ones. As a breather of sorts while I figure out what to do next, I want to move a little away from grammar and do some 成语. Fortunately even just based on the Guardian theme there are no shortage of these, I found 11 in the first episode alone (and probably missed a couple there), so I will be introducing some of these for a few days in here.
