Add a paragraph sign for each paragraph

Add a paragraph sign for each paragraph

Because my supervisor don't like review my papers with pdf format, I have
to find a solution to convert my .tex files to .doc file. However, the
solutions given in many forums beyond my level. So I use the following way
to deal with my problem.
Generating pdf use latex;
Use solid pdf converter to convert pdf to word.
But the generated word file have many problems, such as
Some line-ending words are separated by hyphen "-": (for this, I use
\usepackage[none]{hyphenat} to solve it);
The paragraphs are split to several paragraph by accident. for this, I
want to generate a paragraph sign in pdf file by latex. such as, after
each paragraph, add a paragraph sign (say ppp) in pdf by latex formatting.
With this paragraph sign, I could easily replace ppp to normal paragraph
in Office Word. The question is how?
And, I also want to format the section and/or subsection by adding a sign
(say h1 or h2)
It should be very easy, thanks very much!
