+1) 按⏺️REC掣開始錄音，限時10sec
+(錄音進行中⏺️中間白點會轉成紅色並整個按鈕會閃動就更好)
+2) 按▶️可以重聽錄音
+3) 如不滿意錄音結果，可以按🆖或⏺️REC重新錄制
+4) 如滿意結果，可以按🆗然後在同一頁 或按➡️轉到下一頁開始設定時間
+
+計時器⏱️一共7個，每一個前面放置一個小方格供用家剔選。剔選的話代表要執行，不剔選的話不會執行。
+
+5) ⏱️1號計時器設定為0~30分鐘，用家可自行設定所需時間 (本計時器執行時不會重播先前錄制好的話音)
+6) ⏱️2號計時器設定長度為90分鐘 (啟動後在10~80分鐘期間每隔5分鐘重復播放1組錄音共16組，每組含3次重播1組共30秒完成)
+7) ⏱️3號計時器設定長度為90分鐘 (啟動後在15~70分鐘期間每隔5分鐘重復播放1組錄音共12組，每組含3次重播1組共30秒完成)
+8) ⏱️4號計時器設定長度為90分鐘 (啟動後在40~75分鐘期間每隔5分鐘重復播放1組錄音共8組，每組含3次重播1組共30秒完成)
+9) ⏱️5號計時器設定長度為90分鐘 (啟動後在40~65分鐘期間每隔5分鐘重復播放1組錄音共6組，每組含3次重播1組共30秒完成)
+10) ⏱️6號計時器設定長度為90分鐘 (啟動後在30~65分鐘期間每隔5分鐘重復播放1組錄音共8組，每組含3次重播1組共30秒完成)
+11) ⏱️7號計時器設定長度為90分鐘 (啟動後在10~25分鐘期間每隔5分鐘重復播放1組錄音共4組，每組含3次重播1組共30秒完成)
+
+注意，除⏱️1號計時器外，其他6個計時器是有規定的。只有剔選了排在前面的計時器，才可以剔選(或叠加)排在後面的計時器。
+
+12) 完成時間設置後，可以按▶️開始順次序執行從⏱️1號計時器到⏱️2~7號計時器重播錄制語音的工作
+13) 期間用家可以隨時按⏹️停止繼續執行整個程式 (本程式並不設置暫停功能)
+14) 用家決定結束本程式的話，可以按🏃🏼EXIT離開
+
+
+舉個例:
+
+⏱️2號計時器設定長度為90分鐘 (啟動後在10~80分鐘期間每隔5分鐘重復播放1組錄音共16組，每組含3次重播1組共30秒完成)
+
+我唔知我理解有冇錯，
+我數到係會播 13 次 (組?)，
+我想問下 16 組係點數出黎?
+
+
+
+你呢個黎計我諗我唔會用 app inventor 去做
+於我黎講我會建議寫個簡單 app
+
+個 app 會有兩頁，
+第一頁係 (錄音+計時器)，
+第二頁係設定 (給手戶微調用)
+如果唔係改邏輯 (計時器邏輯) 的話就可以用設定頁去改
+
+一般黎計報價會大約 HKD1200 ~ HKD1400 
+你諗諗先，
+
+想要 app 參考畫面的話可以睇睇呢個帖:

+Q:
+1. 加簡中版本
+2. Logo置中 選擇放左logo下面一至排開
+3. 搜尋酒品後的字體顯示
+4. 酒莊背景的版排改至一眼睇晒
+
+
+A:
+1. 加簡中版本
+
+    - 圖書館
+      - 簡體中文未有頁
+    - 展览-活动
+      - 簡體中文為吉頁
+      - https://www.goyahk.com/展览-活动/?lang=zh-hans
+    - 相集
+      - 簡體中文為吉頁
+      - https://www.goyahk.com/相集/?lang=zh-hans
+    - 巴罗洛葡萄酒
+      - 格式未對齊繁中 / 英文
+      - https://www.goyahk.com/巴罗洛葡萄酒/?lang=zh-hans
+    - 酒庄背景
+      - 內容格式未對齊繁中
+      - 右上菜單未對齊繁中
+      - https://www.goyahk.com/about-wineries/?lang=zh-hans
+      - 酒莊背景
+        - 內容未有 (１３個酒莊)
+    - 右上 menu 未對齊
+    - footer 未對齊
+
+
+2. 想問一下 logo 係指 1 定 2 ？　定其他地方嘅 logo ?
+  ![](./2023-10-11_10-08.png)
+
+3. 你係咪指 1 同 2 之間嘅分別？

+Ref: https://en.wikipedia.org/wiki/Hong_Kong
+
+
+Hong Kong was established as a colony of the British Empire after the Qing Empire ceded Hong Kong Island in 1841–1842. The colony expanded to the Kowloon Peninsula in 1860 and was further extended when the United Kingdom obtained a 99-year lease of the New Territories in 1898. Hong Kong was briefly occupied by Japan from 1941 to 1945 during World War II. The whole territory was transferred from the United Kingdom to China in 1997. Hong Kong maintains separate governing and economic systems from that of mainland China under the principle of "one country, two systems".[f] 
+Originally a sparsely populated area of farming and fishing villages,[18][19] the territory is now one of the world's most significant financial centres and commercial ports. Hong Kong is the world's fourth-ranked global financial centre, ninth-largest exporter, and eighth-largest importer. Its currency, the Hong Kong dollar, is the eighth most traded currency in the world. Home to the second-highest number of billionaires of any city in the world, Hong Kong has the largest concentration of ultra high-net-worth individuals. Although the city has one of the highest per capita incomes in the world, severe income inequality exists among the population. Despite having the largest number of skyscrapers of any city in the world, housing in Hong Kong has been well-documented to experience a chronic persistent shortage. 
+Hong Kong is a highly developed territory and has a Human Development Index (HDI) of 0.952, ranking fourth in the world. The city has the second highest life expectancy in the world, and a public transport rate exceeding 90%.

+1.如果淨係放嗰個txt file佢唔識encrypt 後output 個encrypt後嘅document .即係我如果delete咗wiki_e.txt佢唔識自己再output。需要人手開一個新txt document 
+
+詳情可以睇 Problem1.mp4
+
+2. 1.如果篇文有兩個相同(無論係相同或者多過)字數嘅Alphabet 出現 呢個時候個program就會encrypt錯。例如將「people 」呢隻字打到200字 「P」同「E」嘅數量係一樣 
+所以encrypt完之後變出嚟嘅亂碼 再decrypt唔會變返「People」所以要搵解決方法做到點樣先可以知道decrypt gen出嚟嘅key(k)係準確。
+
+詳情可以睇Problem2 (Alphabet E is the same with P).mp4 Problem 2( Alphabet P is more than E and the guess of Key is error).mp4
+
+阿sir指定話要將呢個problem寫入report睇下點樣solve同埋點解會出現呢個情況. Thanks very much
+
+
+3.個Guildline要求無論係Uppercase定LowerCase都要直接將佢變成Uppercase但係只有文字轉Uppercase標點符號同埋spaces唔會改變。
+
+即係gen出嚟嘅亂碼會係全大階。 （咁係唔係即係delete咗Lowercase段code就得？） 
+
+4.要加多個flow chart喺report入面係整合曬成個program. 
+
+Thanks a lot for helping me.!!!!!!
