xelatex, switching from windows to Mac, Chinese font problems

 之前在windows上的微軟正黑體換到mac上後xelatex就編譯不過了。mac上好像只有黑體沒有正黑體。所以說latex可以獨立於作業軟體mac或windows好像不太對。而且我也遇到不少其它問題。我的mac是macOS Mojave version 10.14.6。

Vim notes

Notes. Useful commands.

1. vim的documentation很爛。看他的documentation真的會瘋掉。好像還是要在網路上找解決方法比較實際。
2. 游標的位置是在游標方塊的左邊，按i insert插入的話，會在游標方塊的左邊插入。如果有兩個游標方塊（比如說游標在{或}上時），游標的位置是在比較深色的那個。在Ｍac上是這樣子。
3. p是貼在游標的右方。P是貼在游標的左方。
4. select/copy/paste/delete
1. select
1. 在我的mac上，我可以在vim裡直接用滑鼠選取文字。
2. 按shift + 左或右 不能選取文字（重要，跟MS Word不同）
3. 按v進visual mode，然後按左右選取。
4. 按ctrl + v，按左右加上下選取。
5. vi) or vi} or vi" or vi' 選取(), {}, " ", ' ' 內的內容，只要游標在裡面就可以。
6. viw can select inner word, cursor anyhwere in the word. And if you continue pressing w, visual mode can continue selecting more words.
7. after v select, you can p paste the info in your register to replace the text v selected. Or you can ctrl v to paste the info in your system clipboard. This works on my Mac.
8. To paste the content you copy from Vim to other programs, in Vim, press "+y$, this yanks the content to the end of line (y$) into system clipboard, paste into other programs with the usual ctrl v. （在Mac上是cmd v）.
2. 
   
3. ciw - change inner word, word includes underscores but not hyphens

1. ci' - change inner content in ' ', without ' '.只要指標在' '裡面就可以。
2. ca' - change outer content in ' ', with ' '.
3. ci} - change content in { }, without }. 只要指標在{ }裡面就可以。
4. ca} - change content in { }, with }
5. 
   
6. daw, cursor anywhere in a word, including the space in front of or after the word.
7. yaw, cursor anywhere, including the space before or after the word.
8. yiw, exclude the space
