Actually, you can also download the visa from this webpage of the website
https://www.travelchinaguide.com/embassy/visa.htm
Meanwhile, this website has links of the officail website of the Chinese embassy in all of the countries where there is Chinese embassy, just click them, and then you will find the application form those official website.
So I don't think there is any need to add the download application form to all of the embassy webpages.
