Looking for a plain-looking XeLaTeX thesis template, for transfer from ClassicThesis template [closed]

I learnt LaTeX for my M.A. dissertation, using the ClassicThesis template. It is beautiful and works fine. But my University (in Vietnam) has requirements on format that are not compatible with ClassicThesis. So I am looking for a template that

1. complies with the University's requirements
• A4 single-sided
• section numbering: 1, 1.1, 1.1.1
• page numbering at bottom
• TimesNewRoman, 13-point, 1.5 line spacing
2. is close enough to ClassicThesis to facilitate the transfer of contents from one template to another.

It's paradoxical to try to do plain (...erm... ugly!) things in XeLaTeX, because the whole idea of LaTeX is to create beautiful books. But that's where I am now: there's no escaping University regulations! This template: https://github.com/zachscrivena/another-latex-thesis-template would be just fine, but it's not XeLaTeX and the packages that I use for language encoding (babel, fontenc) require XeLaTeX. (I use various languages and special symbols.)

I am still a beginner, i.e. unable to change the templates, apart from simple changes such as choice of fonts (and even that is not easy for me).
Many thanks for indications

• That is why one does better not use such convoluted and needlessly complicated boilerplate. To learn more about how to use LaTeX properly, I recommend Marc van Dongen's »LaTeX and friends«. – Henri Menke Aug 15 '16 at 12:51
• Can you perhaps show us your preamble (i.e. everything before \begin{document}). Maybe the necessary changes can be made along with keeping classicthesis. – user36296 Aug 15 '16 at 12:53
• Thanks Henri Menke for your good advice. Yes, I am aware that I am unfamiliar with important principles. – Nguyễn Thị Minh Châu Aug 15 '16 at 17:41
• To Samcarter: Keeping classicthesis does not appear feasible to me because it is designed with great precision in detail (cf. Henri Menke's comment) and the University requirements are VERY different. In any case, here are (i) the passage for non-Roman, non-maths characters and (ii) the full contents of classicthesis-config.tex, the file that contains the Preamble for the classicthesis style. – Nguyễn Thị Minh Châu Aug 15 '16 at 17:48
