  Large-scale language models (LLMs) has shown remarkable capability in various
of Natural Language Processing (NLP) tasks and attracted lots of attention
recently. However, some studies indicated that large language models fail to
achieve promising result beyond the state-of-the-art models in English
grammatical error correction (GEC) tasks. In this report, we aim to explore the
how large language models perform on Chinese grammatical error correction tasks
and provide guidance for future work. We conduct experiments with 3 different
LLMs of different model scale on 4 Chinese GEC dataset. Our experimental
results indicate that the performances of LLMs on automatic evaluation metrics
falls short of the previous sota models because of the problem of
over-correction. Furthermore, we also discover notable variations in the
performance of LLMs when evaluated on different data distributions. Our
findings demonstrates that further investigation is required for the
application of LLMs on Chinese GEC task.
