First, it shows that the overall narration of the novel is existential. Second, from the perspective of Sartrean love, it tries to analyze the love between Jake and Brett. Third, it analyzes the technique “existence precedes essence” in depiction of the characters in The Sun Also Rises. Finally, it analyzes that most of the choices of the heroes and heroines are irrational but they accept the results of the choices in the rational way.

By understanding the past situation, the motives and the characteristics of multinational corporations’ investments in China, we can learn more about the current situation of multinational corporations’ investment in China. On the other hand, by studying the investment strategies of multinational corporations , we can find out the development trend of multinational corporations investments in China. On the one hand, multinational companies’ Investments bring capitals, technologies, knowledge, management skills and corporate value into China, which not only are very helpful to the development of entrepreneurship in China, but also have a positive effect on Chinese economy’s involvement in the world economy. On the other hand, The inflows of multinational corporations’ investments into China, which deepen China’s involvement in the world economy, also pose a lot of challenges, particularly when China’s economic reform has not yet completed. Built on previous results, this paper investigate the current situation and the development trend of  multinational corporations’ investments in China, which will be helpful to the modernization of Chinese economy.
