Everything you need to understand or teach The Land I Lost by Quang Nhuong Huynh.
The Land I Lost consists of Huynh Quang Nhuong's recollections of his boyhood in Vietnam in the 1950s. His family owned a rice farm in an agrarian hamlet. The book covers a couple of years in the very young life of Nhuong, including adventures with many wild and dangerous beasts.
Nhuong had two constant companions during his time at the rice farm. One of these was Tank, the water buffalo, so named because he hit other male buffaloes like a tank during fights over dominance. Tank combined the ferocity of the mountain buffaloes with the obedience and intelligence of the lowlands buffaloes. Nhuong would often ride on Tank's back during his excursions into the woods and around the farm. After Tank defeated a jungle tiger, he was retired from working the farm and tasked with the responsibility of protecting the hamlet's livestock from wild animals.
