I don’t speak nor read ANY Chinese, but I went and looked anyway. You’re using WordPress, so there’s a couple of things I can look for, without needing be able to read the content.
In actuality, the site layout, while typical WordPress, is still easy to read–if you speak Chinese, of course! ?? Lots of whitespace. That’s good for ease of reading.
It’s also easy to navigate, even tho I can’t read it. The header says IT as well as some Chinese words. With that, I can tell that your blog is about HTML, SEO and WordPress and such, which tells me you are sharing what you are know. Bravo. Your categories are well-labeled in English, I can only assume the same can be said in Chinese.
I wonder if you think more graphics might be in order? On each post you make, you can include a picture at the beginning of the post, and it will automatically become a thumbnail (much smaller picture) on the front page where your new posts are listed.
I suggest this because “they” say that pictures help the reader stick with the page instead of clicking away. Old saying: “A picture is worth a thousand words.” I don’t remember who said that.
Since your site is mainly blue/white, wherever you put a splash of an opposite color (on the colorwheel and in the same family “tone” OR one of the pictures mentioned above!), the reader’s attention will be drawn there–like a vacuum cleaner–making it quite the attention-getter. In the case of your site as it is today–orange, yellow and a little bit of red would do the trick. Don’t overdo red. Ever.
