Elk introduction: Elk, commonly known as the "four different animals", was originally unique to China, but was discovered by Father David of France in 1865, and was subsequently transported to Europe. The wild elk in our country have long been extinct, and the last group of them roam freely in the Qing Dynasty Royal Hunting Garden in Nanhaizi, Beijing. In 1900, the Eight-Power Allied Forces carried out crazy looting, the hunting garden was destroyed by the war, and the elk became extinct in China. Around 1900, the United Kingdom collected 18 elk from some European zoos and released them in Ubang Temple Park. Now the elk herd has multiplied to more than 2,000. In 1985, the Marquess of Tavistock in Ubon Temple Park in the UK returned 20 elk to China. They continued to multiply and established a protected area.
