Hi @garygao12580 , if you would like to add zh-mo, please follow
https://github.com/moment/moment/blob/develop/CONTRIBUTING.md

and do

Copy the file src/locale/en-gb.js (or similar) into a new file src/locale/zh-mo.js. Translate everything into zh-mo.
Copy the file src/test/locale/en-gb.js into a new file src/test/locale/zh-mo.js. Translate everything into zh-mo.
Go to the command line, navigate to this project, and run grunt. All the tests should pass.
