Hello:

My comments --

1a) LEFT-most TWO COLUMNS

You now have the
Date
Historical Event

on the left.

There are 20 rows of data under this. 

In particular, I notice that for the Historical Event column, some items are one line, some are two lines, some are three lines or more.

Here is a screenshot --

So, maybe we need to simplify that.



1b) I suggest that the following "two line items" might be simplified as follows --


Japanese Surrender ceremonies in Tokyo
= = = simplify to = = =
Japanese surrender in Tokyo


Japanese Surrender ceremonies in Taipei
= = = simplify to = = =
Japanese surrender in Taipei


United Nations founded in New York city
= = = simplify to = = =
UN founded in NYC


ROC Constitution comes into force in Taiwan
= = = simplify to = = =
ROC Constitution in Taiwan


ROC expelled from United Nations
= = = simplify to = = =
ROC expelled from UN


USA breaks diplomatic relations with ROC
= = = simplify to = = =
USA breaks relations: ROC


Taiwan Relations Act comes into force
= = = simplify to = = =
TRA comes into force


2) SPACING
In 
ROC - USA MDT
and 
ROC - USA MDT cancelled 

Please add another space before 
MDT



3) For the numbers
1st
2nd
3rd

Please try have the 1 as FULL SIZE, and only the st as REDUCED IN SIZE and SHIFTED UP

Please try have the 2 as FULL SIZE, and only the nd as REDUCED IN SIZE and SHIFTED UP

Please try have the 3 as FULL SIZE, and only the rd as REDUCED IN SIZE and SHIFTED UP


4a) After the above corrections are made, you can add two more columns on the RIGHT

4b) The first column to be added is 
Status of ROC in UN

1945.10.24
[label] Sole legitimate government of China
(arrow goes down)


1971.10.25
[label] (Expelled)


1972.02.28
[label] (None)
(arrow goes down)


4c) The second column to be added is 

Status of ROC in view of US government

1928
[label] Recognized legal government of China
(arrow goes down)


1949.12.10
[label] Recognized government in exile of China
(arrow goes down)


1979.01.01
[label] Unrecognized government in exile of China
(arrow goes down)



5) I think the HEADER at the top should have more of a "green" background
See sample on this page --

6)  Maybe you also need to add an extra space after 
USA
in the following items

PRC - USA 1st Communique

PRC - USA 2nd Communique

PRC - USA 3rd Communique
