I'm not really sure if a person gets a choice. If you have a type rating on an aircraft that is not available or no longer available to do your CAAC ATPL, for example, the B747 classic, CRJ900. Then you have no choice but to purchase your own type on the B747-400. If you have your PIC time in say a B767, they have that simulator available in China so you would do your ATPL on that one, and then Jade would type you on the B747-400, then withdraw a big chunk out every month for 3 years, after that time, it would be returned to you. Keep in mind, if you don't have any other prospects and decide to come to Jade as a picc, you will just be a babysitter. Once in a while, you will "be allowed" to take off and land, but it's not regular and it's slightly demeaning, in my experience.
