Guys, do a search on JG in HK Reports.
You will find that:
97.5% of reports are negative. That is because:
1. Most JGs advertised are actually KGs (Korean girls) or something else.
2. Most JGs advertised have many restrictions on what you can do and limited skills.
3. Most JGs advertised give zero, zilch, nada GFE.
4. Most JGs advertised are overpriced at double or more what you pay for a PRC HG.
Go ahead and try one if you must, and don't forget to write a report.
