Unic is another scam agency set up in China. There are dozens of fly-by-night operations like this. Somebodies cousin, uncle, etc. I personally know of zero pilots currently represented by them in China.
Go with Parc or Wasinc. Also Hainan's line training is long and brutal. They probably have the highest failure rate in China. Maybe on earth. There are better options in China.
You pretty much get one shot working in China. You need to choose carefully. Unic/Hainan is a bad combo.
