@lvxiaobu,
The ones about why someone would make numerous similar topics rather than a longer one with all of these related questions in it, in order to try to spark a far less disjointed discussion?
Sorry if that comes across as snarky. You can find your topics by clicking 'My Topics' at the top of each page. Making a bunch of single-question new topics is not a good way to get a good discussion going. Thanks!
