Mac does not take effect after modifying the configuration of the hosts file.

my computer is the Mac OS X 10.10.5 hosts file in the / etc directory
. As shown in figure 1 is my hosts file configuration, IP202.108.22.5 is Baidu home IP address
. I visited test.com using my browser and the result is shown in figure 2
. My browser does not have a proxy computer or a global proxy
. I closed the browser and waited for 2 minutes to open or this page shuts down again
. Running sudo dscacheutil-flushcache on the command line still doesn"t work
. I run ls in the / etc directory | grep host has only hosts and hosts.equiv (empty files)
. My firewall is turned off
. My local nginx and apache are turned off
. / hosts in the private/etc directory is the same as my configuration file
I would like to ask you, what is the principle of this? this thing has not been ready for two days. Please wait online and ask for

urgently.
