Foreigners often make some strange mistakes in Chinese when they study the most difficult language--- ---Chinese. We try to analyze typical sentences to correct these errors.

          Zhè jiàn yìshùpǐn zuò dé xìxì zhìzhì.
False: 这件艺术品做得细细致致。
          Zhè jiàn yìshùpǐn zuò dé xìzhì.
True: 这件艺术品做得细致。

联合式的合成形容词用来表示事物的性质，一般不能重叠，应改“细细致致”为“细致”。
An incorporate adjective in co-ordinate structure describing the property of a thing can not be reduplicated. We change 细细致致 into 细致.
