Placing two identical images in separate parallel columns

Question

I am writing a bilingual pdf with texlive+vscode/xe->bib->xe->xe, and I wanted to insert two identical images in the parallel columns, which was achieved by the following codes, but unfortunately, their positions alway drift to the right side. I have tried \centering \raggedleft \flushleft but failed. Can anyone show me how to modify the codes?

Answer 1

There are extra blanks at both ends of the original picture, just clip it and delete the blanks, then scale by a suitable factor should resolve your issue. I have edited the picture and deleted the blanks as follows.

You may want to take a look at the paracol package. Once loaded, you can execute commands such as

\documentclass[UTF8, a4paper, 11pt]{article}
\usepackage{ctex}
\usepackage[margin=15mm]{geometry}
\usepackage{paracol}
\usepackage{graphicx}

  The world's population is likely to peak at 9.7 billion in 2064, and then decline to about 8.8 billion by the end of the century, as women get better access to education and contraception, a new study has found.
