Hi Zikai,
It’s really nice to read your blog again.
In this blog, each of your questions not only has a clear logic but also has your own unique opinions and sufficient reasons for different problems. Everyone has different learning methods, which are more objective and reasonable. In addition, your hands-on work has also done a great job, which impressed me a lot, well down! Overall, you have satisfied the multimedia principle, split-attention principle and segmenting principle respectively in this blog.
With one small improvement, I wonder if you can increase the font size in your blog so that it will be easier for your readers to read.
To sum up, you have done a good job！
