This is a personal experience to praise the freedom of publishing and expression. When deciding where to publish and print the book, Even though the technology is good enough in Macau, in fact, we want to be close to motherland. But it just happened that the enthusiastic customs officers wanted a sneak peek, so a thousand copies were left as a gift. But should I get back what we have sent out? Or would it be too impolite? Publishers don’t dare to print articles which are too good because they’re afraid that people might steal them. We should therefore practice self-examination, and should not be melancholy.
