Can you please give a little, yet complete, mock-up document with the relevant settings, so we don't have to start from zero?

comment Create Beamer-Theorem like boxes
Right, I didn't mention the library since I always load tcolorbox using \usepackage[most]{tcolorbox}, so I don't have to worry about loading the libraries explicitly.

comment Diagram of an artificial neural network
@phuong the pgf manual has numerous examples and some nice inroductory tutorials: mirrors.ctan.org/graphics/pgf/base/doc/generic/pgf/… There's also a shorter document: cremeronline.com/LaTeX/minimaltikz.pdf (I've never used this last one).

comment Create Beamer-Theorem like boxes
Perhaps you might want to add the breakable option so the box admits page breaks.

comment after using \def I cannot use math formula
@HuangElizabeth I updated my answer providing the definition of a command to typeset limits. Is it something like that what you were trying to achieve with \def?

comment Inserted Picture Position & Picture Size
@perfectionm1ng Yes, I had a little mistake in my code. Sorry about that. I've fixed it in my updated answer. Please use the updated definition of \MyFig and there should be no errors.

comment Ordinal date in section
@wrongusername you need to \protect it only in sectional units (such as in \section, \chapter...) and maybe also in \caption. No need to \protect it in other contexts.

comment after using \def I cannot use math formula
@HuangElizabeth \def is a command used to define macros; normally, only if you know what you are doing you should use it. In your concrete case there's no need to use it; in fact, the way you were using is completely wrong. What do you want to use \def for?

comment Inserted Picture Position & Picture Size
@perfectionm1ng saying just that is useless. What exactly is the error message that you get? What is the code producing this error? Please edit your question and add there a minimal, complete document allowing us to reproduce the problem.
