I'm wanting to say, "I think China is the world's second biggest country." As, in, "I'm pretty sure this is the fact."
I would have originally used 觉得. But apparently this is only for opinions? As in "I think your Chinese is good."
I'm not wanting to say, "I feel" or "I believe", i'm wanting to express that regarding a certain question, I believe the FACTUAL answer is such.
Thanks very much.
