At my old flight school we trained students from several large Chinese Airlines. Our airport would get so busy in the traffic pattern that tower would go crazy. One night I was in the traffic pattern with several other planes from my school and a chinese student I'll call Zhang. Zhang was out on a night solo. Apparently Zhang thought he was the only one in the pattern because he cut us off once, didn't respond to several ATC instructions, and then Zhang got lost somewhere on upwind/crosswind, so tower had to vector him for every leg, downwind, base, and final. To make things worse after his landing "controlled crash" he even got lost on the ground. he wanted to taxi back for another round. Tower told him "NO you STOP and turn your engine off, I've had enough of you and your little games", they called our school for a tug to come tow him back.
