The tap target <a href="article.php?id=11">关于华诺</a> and 1 others are close to other tap targets.
Configure the viewport
Your page does not have a viewport specified. This causes mobile devices to render your page as it would appear on a desktop browser, scaling it down to fit on a mobile screen. Configure a viewport to allow your page to render properly on all devices.
Avoid plugins
Your page uses plugins, which prevents portions of your page from being used on many platforms. Find alternatives for plugin based content to increase compatibility.

Leverage browser caching for the following cacheable resources: (expiration not specified)
Optimize images
Properly formatting and compressing images can save many bytes of data.
Optimize the following images to reduce their size by 7.6KiB (24% reduction).
Compressing could save 3.2KiB (31% reduction).
Minify JavaScript
Compacting JavaScript code can save many bytes of data and speed up downloading, parsing, and execution time.
Minify JavaScript for the following resources to reduce their size by 6.3KiB (34% reduction).
Minifying could save 4KiB (59% reduction) after compression.
Enable compression
Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.
Enable compression for the following resources to reduce their transfer size by 3.5KiB (67% reduction).
Compressing could save 3.5KiB (67% reduction).
Minify CSS
Compacting CSS code can save many bytes of data and speed up download and parse times.
Minify CSS for the following resources to reduce their size by 1.5KiB (25% reduction).
