I have no idea what the process is for getting a Chinese tourist visa outside of America but when I went through the process a few years ago, it was a hassle. They asked for bank records, proof of employment, etc. They also asked for a full itinerary of where I was staying. I just paid for a visa agency to take care of it for me so the process took maybe 2-3 weeks. I know people will go to Hong Kong and go through visa agencies there so maybe that’s a good option for you - no idea if Vietnam has a similar thing going on. The good thing is that the visa lasts for 10 years so if you’re passionate about visiting China you can use the visa multiple times.
