Business minded teachers may understand this more, as it concerns a shell company scam, shell companies pass lots of money through them to clean it as coming from their fake business front, which is ESL schools primarily based in Hong Kong.

SHENZHEN PARTY has ran ads for Green Star, of Shekou, though also teacher complaints now.

This can have serious problems for honest teachers in HK and Shenzhen who file tax returns for their salaries, when they are being put down as working for much higher money in the fake scam company as one of thier "legitimate' employees.

Green Star Resources
Director, Donna Sa
703 - 555 Nathan Road
Hong Kong

This is not a school, Donna never goes there, it is a false project.
For money laundering, HK is the best choice, as the people want the money to end up there, not in Mainland China.

Fake branches:

Zhaoqing, also nothing is here, it piurports to be a school.

Shekou, Seaworld, Shenzhen
2A Bibo Ge, Seaview Gardens, near Taizi Square

This had a little activity, as the director lives here, and rented a large apartment which was registered as a business premise.
The legality around shell companies is spotless, as they want to do large scale banking.
if you do not under stand, shell companies, money laundering, look this up at Google.

Donna ran a few classes of 1 or 2 students, with a few teachers working there, and lost interest in her fake school after a while, and illegally rented out the schoolrooms to local office workers. Many people may do that, it is not so bad as using UK, American, etc passport pages. She implies full time jobs, which is why teachers HAVE to hand over their passports to her.

if a schooll is not giving you a real job, and getting a real WORK visa, not a business visa, which is a new small scam, you NEVER have to give over your passport pages.
