The man page for tmpfiles.d says, of the age field:
"The age field only applies to lines starting with d, D, and x."

So, the line:

d /chenqiang/test_10s 0660 root root 10s

indicates that systemd-tmpfiles should create the directory 
/chenqiang/test_10s, owned by root/root with mode 0660, and periodically 
clean it of files and empty directories more than 10s old.

Note that the default configuration runs systemd-tmpfiles once per day, 
so specifying time periods much smaller than that may not be useful.
