The main difference is Pratt & Whitney in the Far East: the advantages and training system will be better, and it is estimated that it can also be transformed into a big customer in the Far East. Disadvantages, I feel that the competitiveness of products is average, which is not much different from the commercial rental cost of most small and medium-sized pages, and the competition is fierce. The advantage of Far East leasing is low interest rate and fierce internal competition.
