## Course of solving

First, we download the challenge file and extract it. We get a file named `tuning-keyboard-v3_64c92c1d919aa8aa243b1cfcaf1cf8f2`, which is an HTML file, so we open it with browser and IDE to see what is inside.

A few minutes later, We found the disk would move to a specific position and highlight some words. So we record a [video](https://drive.google.com/file/d/1gAqDUGcSSjmi0oaXzH2wx6SKfslWeem2/view?usp=share_link) and write down the highlighted words.
One of our teammates mentioned the challenge title `turning keyboard`, and we focused on the `Input Method`.

We used [DICT.TW Dictionary Taiwan](http://dict.tw/) to search the highlighted words
and found 鳥 is h in DaYi Input Method, 立 is k, 鹿 is c, 一 is E, and so on.
we guess ＝ is 2, 鄉 is _ and 鄉 is _.
Then we created an excel file [TheExcelFile](https://docs.google.com/spreadsheets/d/16ZKRpruNAS2sghU8po1Abjlr1JOdvyPh/edit?usp=sharing&ouid=114731682678227464106&rtpof=true&sd=true)


| origin | decrypted |
|---|---|
| 鳥 | h |
| 立 | k |
| 鹿 | c |
| 一 | e |
| 工 | r |
| 糸 | t |
| 牛 | 2 |
| ＝ | 2 |
| 路 | { |
| 糸 | t |
| 鳥 | h |
| 一 | e |
|... | ... |

We tried to submit the flag, but it was wrong.
After a few times of trial and error.

Our team realized that 靈 would disappear when the disk highlights the `路`. We know it is { since flags start with hkcert22{, and the `街` is }. that means 靈 is the shift key.
So we corrected the excel file:
| origin | decrypted | 靈?|
---|---|---
| 鳥 | h | 1|
| 立 | k | 1|
| 鹿 | c | 1|
| 一 | e | 1|
| 工 | r | 1|
| 糸 | t | 1|
| 牛 | 2 | 1|
| ＝ | 2 | 1|
| 路 | { | 0|
| 糸 | T | 0|
| 鳥 | h | 1|
| 一 | e | 1|
| 鄉 | _ | 0|
| 工 | r | 1|
| 口 | o | 1|
| 女 | l | 1|
| 一 | e | 1|
| 鄉 | _ | 0|
| 口 | o | 1|
| 土 | f | 1|
| 鄉 | _ | 0|
| 立 | k | 1|
| 一 | e | 1|
| 火 | y | 1|
| 鳥 | h | 1|
| 口 | o | 1|
| 女 | l | 1|
| 一 | e | 1|
| 鄉 | _ | 0|
| 木 | i | 1|
| 魚 | n | 1|
| 鄉 | _ | 0|
| 女 | l | 1|
| 口 | o | 1|
| 鹿 | c | 1|
| 立 | k | 1|
| 耳 | p | 1|
| 木 | i | 1|
| 鹿 | c | 1|
| 立 | k | 1|
| 木 | i | 1|
| 魚 | n | 1|
| 手 | g | 1|
| 鄉 | _ | 0|
| 木 | i | 1|
| 革 | s | 1|
| 鄉 | _ | 0|
| 糸 | T | 0|
| 艸 | U | 0|
| 魚 | N | 0|
| 木 | I | 0|
| 魚 | N | 0|
| 手 | G | 0|
| 鄉 | _ | 0|
| 一 | e | 1|
| ＝ | 2 | 1|
| 一 | e | 1|
| 四 | 4 | 1|
| 足 | 9 | 1|
| 金 | 0 | 1|
| 馬 | b | 1|
| 鹿 | c | 1|
| 街 | } | 0|

Again we tried to submit the flag, but it was wrong.
So we tried to change the = to copy the previous word, and it worked.
