This, of course, depends on the woman and the situation, but you want to avoid doing what most guys do, which is to put the conversational burden on her with redundant questions and digging for commonalities. Shoot to do about 75% of the talking, maybe a bit less. Your aim here is to demonstrate your fantastic personality and high value. Try to keep the conversation light, fun, and playful. What conversation starters might you use? There are plenty:  The cocky, playful alpha guy:  "I know you probably get this a lot, but you're absolutely the most stunning woman I've seen..." "My friend had to drag me out tonight, but I'm finally glad he did, because seeing you, right here, right now, was worth it."   The slightly shy, bashful guy:  "I'm sorry this is awkward, but I get really shy around pretty girls." "I'm glad you're still here. I've been working up the courage to talk to you for half an hour, and I was worried I was going to have to embarrass myself in front of you totally sober."   The up-front, matter-of-fact guy:  "Hi, my name is [name], what brings you here tonight?" "This is the part where I introduce myself and you smile and let me buy you a drink, is that right?" "I've been trying to think of an excuse to talk to you, but I got nothing. Can I just tell you an interesting story that happened to me the other day?" Be in control of the conversation, but don’t be controlling. Don’t let yourself slip into interview type questions, like "Where are you from?" or "What are you doing here?" Try to tap into your slightly dangerous, but still controlled, side, and feed off that energy.  If she brings up subjects that you think might steer the conversation down the wrong path, gently push the conversation in another direction. Saying something that has something to do with the topic, but is funny, light, and might bring a change of topic. If she keeps coming back to the subjects you think are leading the conversation astray, you have two options:  Feed off of the energy of that topic, since she seems to want to...

TL;DR in Vietnamese:
Khởi đầu một mối quan hệ, luôn luôn chủ động bắt chuyện. Tránh đề cập đến những chủ đề nghiêm trọng như công việc, chính trị, hoặc bất kỳ điều gì tiêu cực. Dùng thái độ lịch thiệp để vượt qua rào cản quá khứ. Không quan tâm đến kết quả.
