I'm trying to construct a sentence along the lines of, "There were two hard parts...," where I use the existential 有. The issue I'm having is how I convey the meaning that this 'existence' is confined to the past. Should I be using the perfective aspect 了 like:
有了两不好的部分。。。
Or should I include some clause afterwards to indicate the new state of things:
有了两不好的部分。。。现在都没这部分了。
Or is there some other way to do this that I'm missing?
