We absolutely love Jenny Li!!  She goes above and beyond what you ask her to help you with.  My husband John was over there to set up business contacts and she helped with all our requests. and works extrememly hard plus being very knowledgeable.  I would highly recommend her to anyone traveling to Shenzhen, China.  She even managed to get us meetings, tours of gemstone factory and so much more then we hoped to accomplished.  If we could give her a better rating than excellent we would be happy to do so.  She is absolutely the best guide you could ask for.  Thank you  The Silva's   West Michigan Lapidary, USA
