+## InfiniTime 中文支援
+PineTime 現在也可以顯示中文了！  
+這個 InfiniTime 版本增加了 2500 個精選常用正體中文字，注音符號與日文假名，以提供台灣使用者最佳的顯示體驗。  
+安裝了本版本後將可顯示約 98% 日常用語。而超過 2500 字的部份，則可搭配 https://github.com/Boteium/GadgetBridge 來做相似字替換，或注音替換 (也就是會有 2% 的錯別字或注音文)  
+
+因為中文字必須佔用很大的儲存空間，本版本移除了下列功能
+- 天氣 (還沒有錶面支援顯示)  
+- 導航 (GadgetBridge 不支援)  
+- 加速感應器 (僅移除 app. 仍可透過藍芽讀取)  
+- Two (類似 2048 的遊戲)  
+- 錶面: Casio, InfiniTime, PineTime, Terminal (這幾個很佔空間)

+- Navigation (no GadgetBridge support)  
+- Motion (only remove app. bluetooth backgroud service is still preserved)  
+- Two (games)  
+- WatchFace: Casio, InfiniTime, PineTime, Terminal (because they takes a lots of space)
