How to typeset the middle horizontal line of word?

First, set your title "China, Singapore" to the title level. This can be done by choosing Content-Right Click-Paragraph-Indentation and Spacing-General-Outline Level. Any number of levels is ok, but these levels should be consistent.

Next, go back to the cover page and click on the taskbar-Insert-Reference-Index and Table of Contents -Tab Precursor (b)- Select Solid Line.

Finally, you can adjust the font size at will, just a small format.
