said, writing code to a certain stage, more important is to read the code. From the good code to learn the excellent design and implementation, this is from the yard to engineer a necessary stage. when you can appreciate the beauty of software, you have come to a new stage. You can realize the beauty of design, the beauty of architecture, the good design in your eyes is beautiful, not just a bunch of messy but can realize the function of the code, you can be satisfied.
