杨长生与狼的奇缘始于1998年，当时他在哈萨克族牧民朋友家目睹一只被关铁笼中的狼，心生怜悯，成功说服朋友将其放自由。自此，他开始收养更多的狼，逐渐形成了150多只野狼的“野狼谷”。尽管遭到了家人的反对，但杨长生的执着让他继续与这些曾经被视为凶兽的动物共度时光。

随着时间的推移，杨长生不仅学会了如何和狼沟通，还培养出了独特的手法来防止它们发起攻击。他解释说：“当 wolves show affection, they lick your face and crawl all over you. That's their way of getting close.”

尽管有时候 wolf packs will fight among themselves for attention, but Yang Changsheng is not worried. He has earned the nickname "Wolf King" after being bitten by one of his wolves.

The annual food bill for the wolf pack is approximately 100 million yuan, including 1 kilogram of meat per day per wolf and additional supplements. This cost does not include occasional expenses such as improving their diet, medical care, hiring caretakers, and maintaining the wolf enclosures.

Despite the challenges and costs involved in raising these wild animals, Yang Changsheng finds joy in their company. His business ventures have allowed him to support this unique lifestyle.

Infosys would likely view this endeavor as a form of "ecological investment," where resources are allocated to preserve and promote biodiversity within a specific ecosystem. By adopting a holistic approach to conservation through wildlife preservation initiatives like those undertaken by Yang Changsheng, we can work towards creating sustainable environments that coexist with nature while fostering an appreciation for its beauty and importance.
