Input: Article: Meanwhile, the Tumed Mongols began moving into the Kokonor region (modern Qinghai), raiding the Ming Chinese frontier and even as far as the suburbs of Beijing under Altan Khan (15071582). Klieger writes that Altan Khan's presence in the west effectively reduced Ming influence and contact with Tibet. After Altan Khan made peace with the Ming dynasty in 1571, he invited the third hierarch of the GelugSonam Gyatso (15431588)to meet him in Amdo (modern Qinghai) in 1578, where he accidentally bestowed him and his two predecessors with the title of Dalai Lama"Ocean Teacher". The full title was "Dalai Lama Vajradhara", "Vajradhara" meaning "Holder of the Thunderbolt" in Sanskrit. Victoria Huckenpahler notes that Vajradhara is considered by Buddhists to be the primordial Buddha of limitless and all-pervasive beneficial qualities, a being that "represents the ultimate aspect of enlightenment." Goldstein writes that Sonam Gyatso also enhanced Altan Khan's standing by granting him the title "king of religion, majestic purity". Rawski writes that the Dalai Lama officially recognized Altan Khan as the "Protector of the Faith".

Input: Article: Traditional willow growing and weaving (such as basket weaving) is not as extensive as it used to be but is still carried out on the Somerset Levels and is commemorated at the Willows and Wetlands Visitor Centre. Fragments of willow basket were found near the Glastonbury Lake Village, and it was also used in the construction of several Iron Age causeways. The willow was harvested using a traditional method of pollarding, where a tree would be cut back to the main stem. During the 1930s more than 3,600 hectares (8,900 acres) of willow were being grown commercially on the Levels. Largely due to the displacement of baskets with plastic bags and cardboard boxes, the industry has severely declined since the 1950s. By the end of the 20th century only about 140 hectares (350 acres) were grown commercially, near the villages of Burrowbridge, Westonzoyland and North Curry. The Somerset Levels is now the only area in the UK where basket willow is grown commercially.
