This @WRB2022 excursion in 2019 was the most beautiful trip I've ever taken 🤩. Traveling thousands of kilometers through the breathtaking landscapes 🏔️🏜️of #Mongolia and loaking at its #soils. Thanks to @Undurxu for this wonderful trip.
52 хүний 33 нь гадаадын нэртэй хөрс судлаачид. Бүгдийнх нь эв аяыг тааруулаад, 5000 км аялах 17 хоног...гайхалтай байсан ч цөөхөн цаг унтаж, з/б хийсэн дээ. Бүтэн 2 жил бэлдсэн ажил. Эргээд уулзахад ахан дүүс шиг болгодог цаг хугацаа бол хөдөөний аялал юм.
