Im an Australian Landscape Architect and Urban Planner and Ive worked in Southeast Asia, China and the Middle East for the past 12 years.
It has been the most pivotal and positive things i ever did in my life and and I can strongly recommend it to you.
Be aware that working culture in China is fairly hardcore. Very, very, very long hours and scales of projects that dont allow you to do the job you would like to do. Some employers are a bit dodgy but get in touch with people who have worked there through Land8 or Linked In and get the skinny from them.
Other than that expect a whirlwind journey and enjoy the ride…..
