Here's the full info I have for that researcher position:
"We have a USA opening for a Chinese-language annotator position. If you know someone who can legally work in the USA, is able to work 15-20 hours, and is proficient in the written Chinese language, please feel free to forward the attached listing to them. If they are interested, have them contact ext-albert.lin@here.com with their resume."
"Annotator" in this case basically means "work-from-home geographical research." It's the same job I do, basically, only in Chinese: quality control for a GPS/maps company, working from a sheet of guidelines and determining the quality of randomly generated results for various real web searches. It mostly just requires good research skills and patience. Probably pays something like $20 to start-- I don't have that info, sadly-- most likely 15-20 hours a week.
