Too much JavaScript code can slow down your website.

Although it has been confirmed that the speed and statistical code are only somewhat correlated, I still want to delete the site statistics on the blog because it's too hard to use. I will put back the 51 Statistics code, although it may have some impact on the speed. In order to reduce the impact, I also deleted the Google Analytics code that has always existed on the website. After the contract for the Alimama ads expires on the 6th, I will also remove the ad at the top of the homepage. All for the sake of 51 Statistics, I hope 51 doesn't disappoint me.
