+
+## 使用
+
+### 获取番符对应和牌点数
+
+```kotlin
+import mahjongutils.hanhu.*
+
+// 获取亲家X番Y符的点数，返回(荣和点数, 自摸各家点数)
+val parentPoint = getParentPointByHanHu(3, 40)  // ParentPoint(ron=7700, tsumo=2600)
+
+// 获取子家X番Y符的点数，返回(荣和点数, 自摸庄家点数, 自摸闲家点数)
+val childPoint = getChildPointByHanHu(3, 40)  // ChildPoint(ron=5200, tsumoParent=2600, tsumoChild=1300)
+```
+
+### 向听数、进张分析
+
+未摸牌：
+
+```kotlin
+import mahjongutils.shanten.*
+import mahjongutils.models.Tile
+
+// 向听数、进张分析
+val result = shanten(Tile.parseTiles("34568m235p68s"))
+val shantenInfo = result.shantenInfo as ShantenWithoutGot
+shantenInfo.shantenNum  // 1
+shantenInfo.advance  // [3m, 6m, 7m, 8m, 1p, 2p, 3p, 4p, 5p, 6s, 7s, 8s]
+```
+
+已摸牌：
+
+```kotlin
+import mahjongutils.shanten.*
+import mahjongutils.models.Tile
+
+// 向听数、进张分析（已摸牌状态）
+val result = shanten(Tile.parseTiles("112233p44556s127z"))
+val shantenInfo = result.shantenInfo as ShantenWithGot
+shantenInfo.shantenNum  // 1
+shantenInfo.discardToAdvance
+/*
+1z=ShantenWithoutGot(shantenNum=1, advance=[3s, 6s, 2z, 7z], advanceNum=13, goodShapeAdvance=[2z, 7z], goodShapeAdvanceNum=6), 
+2z=ShantenWithoutGot(shantenNum=1, advance=[3s, 6s, 1z, 7z], advanceNum=13, goodShapeAdvance=[1z, 7z], goodShapeAdvanceNum=6), 
+6s=ShantenWithoutGot(shantenNum=1, advance=[1z, 2z, 7z], advanceNum=9, goodShapeAdvance=[], goodShapeAdvanceNum=0),
+7z=ShantenWithoutGot(shantenNum=1, advance=[3s, 6s, 1z, 2z], advanceNum=13, goodShapeAdvance=[1z, 2z], goodShapeAdvanceNum=6)},
+{5s=ShantenWithoutGot(shantenNum=2, advance=[2s, 3s, 4s, 5s, 6s, 1z, 2z, 7z, 7s], advanceNum=28, goodShapeAdvance=null, goodShapeAdvanceNum=null), 
+3p=ShantenWithoutGot(shantenNum=2, advance=[3p, 3s, 6s, 1z, 2z, 7z], advanceNum=18, goodShapeAdvance=null, goodShapeAdvanceNum=null), 
+4s=ShantenWithoutGot(shantenNum=2, advance=[3s, 4s, 5s, 6s, 7s, 1z, 2z, 7z], advanceNum=24, goodShapeAdvance=null, goodShapeAdvanceNum=null), 
+2p=ShantenWithoutGot(shantenNum=2, advance=[2p, 3s, 6s, 1z, 2z, 7z], advanceNum=18, goodShapeAdvance=null, goodShapeAdvanceNum=null), 
+1p=ShantenWithoutGot(shantenNum=2, advance=[1p, 4p, 3s, 6s, 1z, 2z, 7z], advanceNum=22, goodShapeAdvance=null, goodShapeAdvanceNum=null), 
+*/
+```
+
+### 和了分析
+
+```kotlin
+import mahjongutils.hora.*
+import mahjongutils.models.*
+import mahjongutils.yaku.Yakus
+
+val result = hora(
+    tiles = Tile.parseTiles("12233466m111z"),
+    furo = listOf(Furo("789p")),
+    agari = Tile.get("1z"),
+    tsumo = true,
+    dora = 4,
+    selfWind = Wind.East,
+    roundWind = Wind.East
+)
+
+result.yaku  // {Yakus.SelfWind, Yakus.RoundWind}
+result.han  // 6
+result.hu  // 30
+result.parentPoint  // ParentPoint(ron=18000, tsumo=6000)
+result.childPoint  // ChildPoint(ron=12000, tsumoParent=6000, tsumoChild=3000)
