Can travllers get visa on arrival?

Please, could you just clarify what does it mean "singapore flight". I assume that you will be traveling from one country via China to Singapore, but you have to be precise in order to get a precise answer. Also, why did you apply for a Chinese visa? If my assumption is correct, how much time do you intend to spend in Beijing? OK, I hope you will supply some additional information and after that you will get an answer.

Please, could you give some additional details:

1. I understand that your flight has Singapore either as a destination or an origin, but nothing else in between, with just not so clear mentioning of Beijing
2. Again, according to my assumptions, you would like to arrive in Beijing, but you should tell for how long period
3. Maybe you have obtained your Chinese visas in the meantime
