I hope it's ok I share with you a free service I have started called Ringy. Basically, I recognized that A LOT of expats have troubles, both small and big, getting around in Shenzhen (and China) and friends asked me for translation help all the time.
This is actually a great learning experience for local Chinese who have intermediated English and want to practice.
All you have to do is search WeChat official account: ringyringy, and anytime you need help send a message of any content, text or picture (of menu or product). An interpreter will be answering you and assisting you instantly:)
It's seriously free, no catch. Give it a try and let me know what you think.
