Add a new page in latex

When we use Latex, we sometimes need to start a new page to continue writing. Instead of using \ newPage, you’d better implement this using \ ClearPage.
Because:
\newpage: The \newpage command ends The current page.
\clearpage: The \clearpage command ends the current page and causes all figures and tables that have so far appeared in the input to be printed.
In plain English, when you add a large number of new pages, the two are basically the same. When you add a small number of new pages, \ NewPage won’t achieve the effect you want, but \ ClearPage will.
Here’s an example:
Exp1:
\documentclass[twocolumn]{article}
\usepackage{CJK}
\setlength\textwidth{8cm}
\setlength\textheight{8cm}
\begin{document}
\begin{CJK*}{song}
\CJKtilde
first side
\newpage
sorry, first side
\clearpage
\end{CJK*}
\end{document}

Exp2:
\documentclass[twocolumn]{article}
\usepackage{CJK}
\setlength\textwidth{8cm}
\setlength\textheight{8cm}
\begin{document}
\begin{CJK*}{song}
\CJKtilde
first side
\clearpage
haha, second side
\clearpage
\end{CJK*}
\end{document}
