It's always hard to make choices, and harder to know which goal you could fulfill. A not high grade sometimes makes one disappointed, but he can choose. Sometimes choses count more than fundamental conditions.
So I make a choice of what I want to study in my post-graduate life, although I am still just Junior,the ocean engineering. The earlier to choose, the easier to success, isn't it? I think ocean would play an important role in the 20 years, no matter in China or any other countries around the world. The oil, the structures offshores and the wave energy can bring direct benefit to humans. I consider it more interesting than what I am learning, hydraulic engineering, which is mainly to construct dams, while I don't like them at all.
By the way, pay 840 RMB for a air ticket from Peking to Guilin, at 16th this month will I be at home! Really excited!
