Two days in Opatija, and then set off for Austria. Passing through Brad of Slovenia, I revisited the Sound of Music and stayed in the beautiful Grundel Lake area. Walking in the morning, the lake and the mountains are all covered with smoke and mist, the wonderland where the Avalon spirit is hidden, even people who are used to convenient cities like me can't help but think, if I can stay here all the time, calmly and slowly end up old, how good?
