Chengyu Chain Generator

How to Use Chengyu Chain Generator

Chengyu Chain Generator creates an idiom chain from a starting chengyu. Enter the first idiom and choose a target length. The tool then looks for an unused idiom whose first character matches the previous idiom’s final character.

The result shows the generated chain and whether the target length was reached. If the chain stops early, the local idiom list simply ran out of available matches for the next character.

Formula & Theory - Chengyu Chain Generator

previousLastCharacter = last character of current idiom
nextIdiom = first unused idiom whose first character equals previousLastCharacter
repeat until target length or no match

A chengyu chain can be modeled as a graph. Each idiom is a node. A directed edge exists when the last character of one idiom equals the first character of another idiom. Generating a chain is a small graph walk with a no-repeat rule.

This front-end version uses a local list of 3,000+ four-character chengyu, giving the generator broader first-and-last-character coverage for more reliable chains.
