I couldn't use a lot of things between the lack of a readily accepted payment method and the fact I don't speak or read chinese (using the term 小笼包 is a nice way to show that you apparently have language skills).
My conclusion is to write off the place because I did not enjoy visiting it (urban sprawls are not my preferred habitats) and that even a business trip is a lot more hassle than most other places. The combination of payment, language and a huge cultural difference makes it just not worth it to me.
