I have a long document (in Vietnamese) with many \subsections. I have a problem like this image. I have two questions:
1. How can I set a space biiger at \section and \subsection in tableofcontent;
2. How can I set lowercase instead Uppercase, e.g Contents instead CONTENTS

1. you can use `\setlength{\cftsecnumwidth}{...}` and `\setlength{\cftsubsecnumwidth}{...}` to set the space for the section and subsection numbers in the toc
2. you can redefine `\renewcommand{\cftmarktoc}{\@mkboth{\contentsname}{\contentsname}}` to change the contents name in the header
