The Qinghai Tibetan Culture Museum is well worth a visit, with its South and North wings each having their own focus. Its crown jewel is the Guinness World Record-holding 618-meter-long painted Thangka, created with natural mineral pigments and breathtaking detail. Other exhibits include Tibetan medicine mandalas, traditional costumes, ancient books and ritual implements, comprehensively showcasing the history, medicine, and customs of the Tibetan Plateau. Renting a guided tour is highly recommended to allow for a leisurely appreciation of Tibetan civilization; it's an excellent place in Xining to gain a deeper understanding of Tibetan culture.
