## What it is
A curated collection of commonly used regular expressions, documented in Chinese, covering email, phone numbers, domains, IPs, account names, character classes, and numeric patterns. It serves as a reference/cheatsheet rather than an executable library.

## Use cases
- find a regex to validate email addresses
- regex for validating Chinese mobile phone numbers
- regular expression to match IPv4 addresses
- regex to validate usernames with letters, digits and underscores
- pattern for matching Chinese characters
- regex for integers and floating point numbers
- copy-paste regex for domain name validation

## When to choose
- you need quick, ready-made regex patterns for common validation tasks
- you want a browsable reference of regex examples with test cases
- you work with Chinese text and need patterns for Chinese characters or phone formats

## When to avoid
- you need a regex library with programmatic APIs or runtime validation
- you need RFC-strict validation (e.g., fully compliant email parsing)
- you need actively maintained patterns or multi-language documentation

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: parser, developer-tools
- domain: developer-tools, web-development, parsers
- platform: cross-platform
- tags: regex, cheatsheet, regexp, validation-patterns, chinese-documentation
