Glowing light swoops down lands atop mountain emits bright lights then chased off by 6 silent helicopters with green lights

I watched a ball of light that had a aura of light blue light glowing around it come down fast at 45 degree angle with very small comet like tail it swooped like a Nike symbol stopped 4,000 ft up or so started glowing even brighter then it took off over top of Chinese peak mountain. 5 minutes later I look over and it’s either landed or hovering just above the mountain rite next to a bunch of antennas on the mountain glowing super bright an now had a glowing fireball of light to the side of it. About 10 mins went by of it pulsing glowing. Then all the sudden glowing balls dimmed out and 6 to 8 helicopters with green lights on them popped up out of no where they must have came from other side of mountain they went back and forth in the general area of where the ufo was sitting for less then 5mins then all helicopters took off in line formation to the west but the odd thing was I did not hear a single helicopter I was watching them fly around multiple helicopte! rs but did not hear any noise at all.
It was rather odd contact me via email if needed
