I'm not trying to improve or change your writing, just suggest corrections. Also, be careful using very long sentences. Your 2nd paragraph is one long sentence.
*Furthermore*, during my internship at China Daily, I found that storytelling can also be a way of advertising. For example, in the report “sisters of Yao in Guangxi: we come from Yao mountain and now we come back to it”, we used a girl's moving story to show the *characteristics of (‘a’ or ‘the’ or ‘her’)* minority culture, to help the ethnic minority villagers to get rid of poverty by letting more people know *about* their cultural industry. When researching and writing the report, I tried to identify the topic, angle *(or ‘viewpoint’)*, and way of expression that the international audience *would* like. It turned out to be well-received and many global audiences said they wanted to visit there.
After graduating, I have been working at XX company which has frequent business exchanges with countries around the world for a year and a half so far, and in the process of working with customers on products as an account manager, I have found that advertising plays a very important role *(not needed, “in the stage”)* when customers become interested in a product, understand its characteristics, and finally decide to buy it *after comparing with* competing products.
