On the first day of shooting, the film crews were all very excited, relaxed and treating it as a holiday tour.
On the second day of shooting, the film crews were beginning to feel a little tired.
On the third day of shooting, the first casualties started appearing, with some staff from all three film crews falling sick at the same time. Some either caught a cold or couldn't acclimatize, with one suffering from altitude sickness, but was recovering well after being given an oxygen mask at a local hospital.
On the fourth day of shooting, the film crews were all complaining incessantly.
"We still have to fly today?"
"We're going to Guizhou this time?"
"Fuck me! I can't take this anymore!"
"Director Zhang, can we request for a day off to rest?"
