那位高人帮我看看这段英文有什么语法错误!

In conclusion,the dragon boat event is a traditional Chinese celebration since 278 BC to commemorate the patriotic poet Qu Yuan,and to ward off epidemic diseases and evil spirits.
It represents a traditional Chinese ritual,a life-style of the ancient Chinese,and full of “re’nao” (hustle and bustle).
Different age groups of people participate in the event with different ways.

Besides,finding shows that this event also contributs to popularizing traditional Chinese culture and promotion of local tourism industry.
给你点意见,这应该是一篇英文essay 通常情况下,CONCLUSION只是一个对全文大体意思的总结,也可以作为introduction的一个复述,所以在conclusion里,尽量不要举例和具体说明,只需要用连词把几句话串起来就可以,一般不超过100-150字,那几句话就是你文章正文段落的中心思想.
所以我建议
Different age groups of people participate in the event with different ways.
For example,adults usually row the boat to enjoy the competition,while children and aged people watch the race and have chats with friends.However,the specific ways of celebrating around China is different due to regional differences.
这段,改为：Different age groups of people participate in the event with different ways,while people from different regions also have their own ways of celebration.
