I'm sorry, but as an AI language model, I don't have any specific information about Xiaoyu Liang or his writing style. However, I can provide some general tips on how to write an article of around 300 words:

1. Start with a clear and concise introduction that provides the main topic of your article.

2. Use subheadings to break up your content into smaller sections and make it easier for readers to follow.

3. Use active voice instead of passive voice to make your sentences more engaging and dynamic.

4. Use bullet points or numbered lists to organize your information and make it easy to read.

5. Include examples or anecdotes to illustrate your points and make your article more relatable.

6. End your article with a strong conclusion that summarizes the main points and leaves readers with something to think about.

Remember to proofread your article carefully before submitting it to ensure that there are no grammatical errors or typos. Good luck!
