Thank you for your concern. I switched to another Taiwanese lawyer. He is very professional and high efficient. Since he can spean Mandarin, I feel very comfortable as well. I feel very lucky to find out Wu is bad at the very beginning.
If for any reason, Wu cannot do something good for you this time, forget about him. Try to find somebody responsible. If you need my lawyer's information, just send me an meail.
All the best!
