It went through a golden age in the late 1970s and 1980s when successively brilliant animation work was produced. Here are 10 mustsee classics from China39。s natural scenery. Pleasant Goat and Big Big Wolf【喜洋洋與灰太狼】 Pleasant Goat and Big Big Wolf (Chinese:喜羊羊與灰太狼) is a Chinese animated television series. The show is about a group of goats living on the Green Pasture, and the story revolves around a clumsy wolf who wants to eat them. It is a popular domestic animation series and has been adapted intoBeijingStudio. In the 1980s the series was one of the most popular animations in China. It was released at a point when the Chinese animation industry was in a relatively downed state pared to the rest of the international munity. Still, the series was translated into 7 different languages. The episodes were produced with a vast amount of papercut animations.
