Who can afford a US lawyer?
A Chinese tourist that can leave the country is probably pretty well off. Also lawyers for these types of cases work on a contingency basis, getting a percentage of any award for little to no upfront costs. And language isn't an issue either, there are a number of Chinese law firms in California and NYC.
Anyways I doubt that story, particularly without some sort of hard news article, Chinese social media is well known for their made up stories.
