I know the site but i never payed that much attention to the text size because i'm not learning Chinese. Yes it's weird that everything is an image. I started using this Chinese handwriting input site to get characters as text, but that's obviously impractical if you need more than a couple characters.

The text size can be improved by zooming in the page. On Firefox (default in in mostt DEs, i think) you hold control and scroll up or press the plus key.

I wonder if the site is so old that it was written before there was a better way to display Chinese in HTML. I don't know any of its history tho.

Maybe CtrlShift+ or Ctrl+MouseWheel? It work for me to enlarge the page.

I think that website is just very old, so they made everything as images instead of trying to get chinese characters rendering on early browsers.

How does this show up? 典
