The province Quebec succeeded in keeping its French cultural identity in the English ocean of North America by two means.On the one hand,Quebec made language laws to strongly protect the purity of its French language.Learning from this point,we can keep a clear mind to develop our country's culture industry by resisting the sweeping "English heat".On the other hand,there are still many restrictive factors in Quebec's "de-colonization" because of the close connections between Quebec and North America,which no doubt rings the alarm to the "desinification" of Taiwan's secessionists.
