Salut,
I find the story line a bit strange..... the story seems to be about the guy learning about "authentic" Chinese food, but the food practices in the rest of the story was also quite "off". It doesn't bother me so much even as someone from that culture as the goal here is the French practice. I'd just read it as something written without much knowledge....
If you ever decide to make the story line more consistent, Tsingtao is a much more popular Chinese beer than Tiger, which is a Thai beer. And I guess the digestif is acceptable if it's a must for a French customer, haha, even though it's not so common culturally.
Thanks for reading.
