Can I use my existing China 10Year M-visa to go for a holiday/vacation in China?

US citizen and passport with a currently active and valid M-visa that I use to visit our factory in Jiangsu.
I want to go for a summer holiday as a tourist but I cannot get any guidance on whether I can use my M-Visa or if I need to get a new L-Visa (which I think will cancel my M-Visa and I'll need to get a new M-Visa when I come back to USA). Can you offer any guidance as I much prefer the simplest path of using my existing M.... ?
Thanks.
