Thank you for your comment. Maybe it's because I have poor cold tolerance, so I feel quite cold there. We drove motorbikes from Ngoc Hoi district - Kon Tum Province, it took more than 5 hours to get to Da Nang, we had to go to Hue city on time (where I registered to study) to register in the dormitory, so we missed enjoying the beautiful scenery here. But next time will probably stay here longer.
