That solves the problem. Thanks Omid.

Should this be the default setup? It seems more nature to fontify the src block than not.

Also, when I export the org file to html, the src block is not fontified in the resulting html webpage. Is there another option to turn this function on? Thanks.

Hi Shiyuan,

Add

(setq org-src-fontify-natively t)

to your .emacs.
