Is the font of the word "Beijing" in the emblem of the 2008 Beijing Olympic Games "Chinese Seal Dancing Beijing" a seal or an official script?

This pattern does not have the characteristics of official script. Regarding the specific characteristics of official script, you can go to Baidu Encyclopedia to check the entry of "official script".

It is close to seal script in form, but not the "capital" of seal script.

In fact, this pattern refers to the form of seal cutting and transforms the word "Jing". There is a big gap with the word "Jing" in seal script, but it is closer to the word "Wen" in seal script.
