6 miles on the ILS into SHA, we are asked to make left orbit "for separation" (traffic in front still 5 miles ahead on TCAS). We're going down on the glide at this point. Whilst we're busy with our "WTFs" for 3 seconds, the instruction is repeated with "expedite". Skipper at the time, pushes to level off and completes the turn in heading. In the debrief we discuss how stupid this was due to uncertainty about obstacles.
60 miles into Nanning, we get asked to reduce speed to 180Kts and make 2 orbits. Flaps go out. After completion of orbits, resume normal speed, retract flaps, fly for another 30 miles then sequence for landing.
At Wenzhou, we get asked to line up with an aircraft on short finals (2-3 miles). We protest, and are met with "aaah ok, hold, hold, confirm holding short!". Two days later exact same thing happens at the same airport.
Cruising at circa 30k, told to hold position. "How long is the delay?", answer: "Undetermined". 30 minutes later, "Undetermined". We asked to go back, "OK, resume course".
