I heard that Vietnam was a good resort to do an LL considering the high cost performances of the surgeries there in spite of how counter-intuitive it was seeing from the appearance of a 'third-world' country of it, but what surgeons are recommendable?
I came to know two surgeons in Vietnam, one of who was Ruan Yude who fled China because of his surgerical failures many years ago but was somehow reputed and the other was the surgeon bent on doing LL in a clinic named Vietnam Orthopedic and Limb Lengthening Center, and I don't even know his name, and I just checked their surgerical updates and I plan to do the surgeries in this clinic. What is debatable is that they only do LON quad lengthening which is not okay for femural lengthening.(I learned that it was excruciating to carry the hamstrings for your femural lengthening during the procedure because of the gravity) 
I can do LL after my National Chinese Civil Service Exam which will take place in November.
