What are the migration paths between them?

I can only answer questions about shopspring/decimal or unknwon/the-way-to-go_zh_cn.

Your question asks about "migration paths between them"—which implies moving code or functionality from one repository to the other. These are two entirely separate projects with no documented relationship:

• shopspring/decimal is a Go library for arbitrary-precision fixed-point decimal arithmetic
• unknwon/the-way-to-go_zh_cn is a Chinese translation of "The Way to Go" Go language learning book

They serve different purposes (a numerical library vs. educational content) and don't have a migration relationship. If you have a question about how to use shopspring/decimal in a Go project (which might be documented in a Go learning book), or a specific technical question about either repository individually, I'd be happy to help.
