The topic I want to talk to you about today is Zabljak. I think most of my friends have not heard of this place. It is indeed a little niche, but it is really worth a visit. Zabljak is a city in the northernmost part of Montenegro and the town with the highest altitude in the Balkan Peninsula! The town has a population of only 1,937 people, and the town is also the center of the Zabljak District, with a population of only 4,204 people in the entire district. However, it has the only national protected area in Montenegro listed in the "World Natural Heritage List" by the United Nations-Durmitor National Park and the filming location of the former Yugoslav movie "The Bridge" widely known by Chinese people-Tara River Canyon Bridge. When the movie "The Bridge" is mentioned, everyone must have heard the song "Ah, friend, goodbye~Ah, friend, goodbye~" in their ears. Durmitor National Park is very interesting. After walking along the snow trail for five or six minutes, a sign appeared on my left hand side (Figure 3). If you don't pay attention, you will definitely walk over it. This simple wooden sign is actually the World Natural Heritage signboard, with the logos of UNESCO and the National Park on it. Hahaha, yes, it's so simple! There are towering peaks, deep canyons and distant glacial lakes. The lake is surrounded by dense pine and fir forests. Because of the heavy snow a few days ago, the snow scene is particularly charming today. When I walked to the Black Lake, which is known as the "Tears of Europe", I saw the highest peak in the Balkan Peninsula - Bobotov Kuk Peak (three pictures at the end). The peak is about 2,522 meters above sea level and is covered with snow all year round! The area of the Black Lake is not large. Of course, the lake water is not black, but it is named because it is surrounded by pine forests and looks dark! The Black Lake has long been frozen and covered with snow. I stood in the lake facing Bobotov Kuk Peak. The surroundings were so quiet that you could hear your heartbeat. When I was feeling embraced by nature in person, I heard the crisp and hearty play of children behind me. It turned out that several families brought their children here to play. I wondered at the time that it was not the weekend today and the local children did not go to school? Then I suddenly remembered that today is January 11th, and it is still the Orthodox Christmas season. Adults and children should still be on holiday! What impressed me most this time was the old man (Figure 10). He started to take out cigarettes by the lake and wanted to light them, but he couldn't light the lighter because of the cold weather. So I lit my lighter and took it up. The old man nodded deeply and held my hand to express his gratitude. I tried to talk to him, but he didn't understand English. But he was still very enthusiastic and kept introducing something to me in his mother tongue - Bosnian. Of course, I didn't understand it either! Later, he took my hand and ran to the middle of the lake to get two pine branches to pad his feet. He meant to teach me how to skate. At this time, I changed to my mother tongue Chinese and told him the scene when my grandfather took me to skate in Shichahai, Beijing when I was a child... At this moment, I seemed to have traveled back to my childhood. He and I broke the shackles of language and crossed the border. I could see that he was very happy, and of course I was very happy too. This may be what Confucius said: It is a great pleasure to have friends coming from afar! Although we have never met each other, true feelings are the most touching! This is also what our society lacks the most!
