Add automatic submission to search engine functionality.

We've added the following new features:

First: Add a QR code display function to the page to facilitate sharing

Second: Add the search engine automatic submission function. All Posts accepted by us will be automatically submitted to search engines such as BING for inclusion.

Third: Modify the display time of the page to UTC 0 time zone for international events。

I'm working hard to make a success, and I hope it can bring you real and meaningful help.
