Are there any horror movies about young men and women traveling?

Introduction:

A couple climbs a snowy mountain with their teammates, and the weather suddenly changes in the middle, but the team members insist on going up the mountain, so their boyfriend (Ng Cheuk Hai) leaves his girlfriend (Deng Lixin) to guard the camp. After climbing the mountain for three days, there is still no news of the climber. Seven days later, everyone came back except her boyfriend. The team members said that her boyfriend was crushed to death by an avalanche on the first day of the peak! They came back before the first seven, thinking that their dead boyfriend might come back for her. In the middle of the night, my boyfriend appeared covered in blood, grabbed her and ran away, telling her that the first day of climbing the mountain had a mountain disaster! Everyone else is dead, but he is still alive. Who the hell are they? Who's a ghost?
