Try getting into regional with more CRJ flying. Get PIC time and applying for China Express, go from there.

Or try direct interview with those Chinese airlines, they have paid training program, once you get your multi-commercial you will intially start with B737/A320, and flying international widebody within only 5 years.

Or get your Commercial/instructor rating, get into GA gig in China(mostly flight training), get additional 500hrs TT and applying those Chinese Legacies.

If you thinking about go from american regional airlines and upgrade to legacies, get your B737 /A320 pic time and apply, you are too old to apply. The maximum age applying for those Chinese Legacies are 40.
