## Overview

The red dragon carries the character 中, center, and a triplet of it scores 1 han from any seat in any round. That unconditional value is the whole appeal: unlike winds, chun never goes stale when the round changes. Hold a chun pair early and you hold a decision. Pon the third copy and you have an instant legal open hand, often the fastest win available; keep the hand closed and the pair still adds 2 fu while leaving riichi on the table. Chun also carries a warning label for the table: once a red dragon triplet is exposed next to another dragon set, opponents should assume shousangen or daisangen is live and tighten up accordingly. Discarding a lone chun late against a dragon-heavy hand is one of the classic ways to deal into a monster.

## Conditions

- Your hand must contain a **triplet or quad** (three or four copies) of **chun** (red dragon, 7z)
- The triplet can be **open or closed** -- you can call pon on a discarded red dragon
- The rest of your hand must form a valid winning hand (three more melds and a pair)

## Strategy Tips

- Red dragon is arguably the most recognizable tile in mahjong. Experienced players watch chun discards very carefully. If you're collecting them, expect opponents to be cautious about discarding the third one.
- Holding all three dragon types (haku, hatsu, chun) opens the door to shousangen (little three dragons, 2 han) or even daisangen (big three dragons, yakuman). If you start with pairs in two dragon types and a triplet in the third, consider pursuing the bigger hand.
- If your starting hand has a single red dragon with no clear path to a pair, discard it early. Holding a lone dragon tile wastes space in your hand and risks dealing it into someone else's pon later when it's more dangerous.
