İntegral symbol style

amsmath

How can I make the integral symbol as without removing the \usepackage{MnSymbol}?

I want this but I don't want to remove the \usepackage{MnSymbol}.

enter image description here

\documentclass[a4paper]{article}
\usepackage{amsmath}
\usepackage{MnSymbol}

\begin{document}
\[ \int 3\,dx\]

\end{document}

May be try this package:

enter image description here

\documentclass[a4paper]{article}
\usepackage{amsmath}
\usepackage{MnSymbol}

\usepackage{esint} % various fancy integral symbols
\begin{document}
\[\int \iint \oint \oiint \varoiint \]
\[ \int 3\,dx\]
\end{document}
