According to what I know, the Chinese version of Haruhi Suzumiya's series from Coral Library isn't authentic. In the mainland of China, any unauthorized translation is not allowed because it may violate the copyright of the original author. Therefore, Coral Literature's Chinese version of Haruhi Suzumiya's series should be regarded as pirated works. If you wish to obtain the original Haruhi Suzumiya series, it is recommended that you purchase or download the original works in the mainland of China.
