+    models, corpus and leaderboard. Here we bring in classification task of CLUE, which are AFQMC, TNEWS, IFLYTEK,
+    CMNLI, WSC and CSL.
+
+    Args:
+        dataset_files (str or list[str]): String or list of files to be read or glob strings to search for a pattern of
+            files. The list will be sorted in a lexicographical order.
+        task (str, optional): The kind of task, one of 'AFQMC', 'TNEWS', 'IFLYTEK', 'CMNLI', 'WSC' and 'CSL'.
+            (default=AFQMC).
+        usage (str, optional): Need train, test or eval data (default="train").
+        num_samples (int, optional): number of samples(rows) to read (default=None, reads the full dataset).
+        num_parallel_workers (int, optional): number of workers to read the data
+            (default=None, number set in the config).
+        shuffle (bool, Shuffle level, optional): perform reshuffling of the data every epoch (default=Shuffle.GLOBAL).
+            If shuffle is False, no shuffling will be performed;
+            If shuffle is True, the behavior is the same as setting shuffle to be Shuffle.GLOBAL
+            Otherwise, there are two levels of shuffling:
+
+            - Shuffle.GLOBAL: Shuffle both the files and samples.
+
+            - Shuffle.FILES: Shuffle files only.
+
+        num_shards (int, optional): Number of shards that the dataset should be divided into (default=None).
+        shard_id (int, optional): The shard ID within num_shards (default=None). This
+            argument should be specified only when num_shards is also specified.
+
+    Examples:
+        >>> import mindspore.dataset as ds
