[done] please combine - principles of economics

[Yiwei]

Hello!
N. Gregory Mankiw’s Principles of Economics was published in China as two separate volumes:

Principles of Economics: Microeconomics (link: https://www.goodreads.com/book/show/2...)
Principles of Economics: Macroeconomics (link: https://www.goodreads.com/book/show/3...)

Could you please merge these two Chinese-language volumes into the “Other Editions” of the main Principles of Economics page? Thank you so much for your help!

That is not how we do it on Goodreads, if a larger work is split into volumes each volume is treated as a different work.
