Three ways are highly recommended in general. No.1, it has got to do something with the free public resources, you might know more about it, the Internet. Since millions of useful information and messages can be found online, ranging from academic studies to history, from astronomy to philosophy. Almost everything you want to know could be found online. No.2, the college library or city library cannot be ignored. Those who are hoping to have a clear view of history or other kinds of information need to visit this sort of place more often. No.3, it must be from the mass media, such as radio, TV, magazines and newspapers. Since it is a traditional way for us to get news. Like finance and economy for example. So, that is it.
