不是Beijing is the capital of China,which is known to all.这里which代表前面整句话,你要表达相同意思的话,只能分两句写：Beijing is the capital of China,and it is known to all.当中用and来连接你用非谓语表...可以，因为wanting to....修饰的是people=people who want to....定语从句里面有一种非限制性定语从句他是对前面进行补充说明，而且一般都很长所以不用非谓语转化限制性定语从句，都比较短，翻成“....的”people wanting to ....,想买房的人，可以用非谓语来表示
