这是我无聊时写的一个小程序，欢迎大家点评（运行时无错误）！比如可以简化一些部分吗？

还有一个版本：
class China:
    def __init__(self):
        print("\tChina is so great!")
        
    def coverpollution(self, cover, population):   
        self.cover = cover
        self.population = population
        print(f"\tChina has about {self.cover} covers. ", end = '')
        print(f"China has about {self.population} populations.")
        
    def moutains(self):
        print("\tChina has a lot of moutains.")
        
    def famous_moutain(self):
        print("Mount Huang is famous.")
        
    def rivers(self):
        print("\tChina has a lot of rivers, too.")
        
    def famous_river(self):
        print("And Huanghe river, Yangze river is famous, too.")
        
    def love_China(self):
        print("\tI love China!")
        
the_China = China()
the_China.coverpollution(9600000,1400000000)
the_China.moutains()
the_China.famous_moutain()
the_China.rivers()
the_China.famous_river()
the_China.love_China()
