I recall 2 757s being repaired on the apron in Kunming in 1991 or '92 following heavy landings, apparently nose wheel first. In both cases, only a few months apart. A bamboo hangar was built around the nose area back to the leading edges and covered with strippey plastic sheets. Teams from Boeing did the work on the apron area., they took a couple of months in each case.
Being 7000' AMSL we were warned about flaring early at Kunming.
