It can delete dir if the age > 10s, but can't delete the files in it. 

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.
