A solo travel guide covering 5 provinces and 6 cities in 14 days (low-energy version)

I had some free time during my annual leave, so I decided to just pack my suitcase and go. The route was (Xi'an → Luoyang → Qingdao → Dalian → Shenyang → Changbai Mountain). Xi'an (3 days): Day 1: Hanfu experience + photos at the Bell Tower and Drum Tower; Day 2: Visiting various museums in the city + strolling along the city wall (didn't manage to book a visit to the Shaanxi History Museum). Day 3: Terracotta Warriors (highly recommend hiring a guide) + evening high-speed train to Luoyang. Luoyang (2 days): After arriving by high-speed train in the evening, I checked directly into a hotel near Yingtianmen. This allowed me to easily visit and take photos of Yingtianmen. Day 1: Laojun Mountain: I joined a small group tour and joined the tour right outside the hotel. Day 2: Longmen Grottoes: I got up at 10 am, packed my bags, and set off for Longmen Grottoes around noon. I left my luggage at the entrance of Longmen Grottoes so I could easily take a taxi to Longmen High-Speed ​​Railway Station when I returned in the evening. Qingdao (3 days): I arrived in Qingdao in the evening and checked directly into a hotel near Zhanqiao Pier. Day 1 Zhanqiao Pier → Cathedral → Qinyu Road (tour) + went to Old Jack's Bar for drinks in the evening and bought a great export coat for only 200 RMB. Good quality. Day 2: Badaguan Scenic Area → Beach Day 3: Early morning trip to the airport to fly to Dalian Dalian (1 day): Didn't have much time because it was mostly sightseeing. Day 1: Bangchui Island → Fisherman's Wharf → Cross-Sea Bridge → Yifang Castle → Pinhailou Restaurant (delicious). Arrived in the morning, put my things in the hotel and rested. Departed in the afternoon, and saw the Cross-Sea Bridge at sunset. Day 2: Morning trip to Zhongshan Square to feed the seagulls, then took the high-speed train to Shenyang. Shenyang (1 day): Only dared to do one thing in Shenyang: experienced Qinghe Peninsula Bath Center + ate Handu BBQ (so delicious, you must try it! Handu BBQ is incredibly delicious!) Changbai Mountain (4 days): Skiing + Water Park + Massage Spa + Hanla Mountain Hot Spring + Rime Water Rafting After taking the high-speed train to Changbai Mountain Wanda Ski Resort, the vacation began. My daily routine consists of skiing, playing in the snow, and eating (though there's nothing particularly delicious).
