They simply say China, Taiwan, Hong Kong andor Macao. They simply say China, Taiwan, Hong Kong or Macao.

Your meaning is obvious and makes sense. However, a person is probably from 1 of these places and not from all 4, so you would use "or".

They simply say China, Taiwan, Hong Kong, and Macao. They simply say China, Taiwan, Hong Kong, and Macao.

You need the comma to separate Hong Kong and Macao, otherwise they may be seen as the same entity. For example, Trinidad and Tobago is the name of a single country so a comma would not be put before the 'and' separating 'Trinidad' and 'Tobago'.

They simply say “China”, “Taiwan”, “Hong Kong”, and “Macao”. They simply say “China”, “Taiwan”, “Hong Kong”, and “Macao”.

(When they say China, they in factare referring to mainland China). (When they say China, they are referring to mainland China).

But in some situations, for example, youwe met overseas and you asked me where I was from. But in some situations, for example, we met overseas and you asked me where I was from.

But inthere are some situaexceptions, for example, youif we were to meet overseas and you asked me where I was from. But there are some exceptions, for example, if we were to meet overseas and you asked me where I was from.

'But in some situations' on its own doesn't make sense. You would have to add on something like: 'But in some situations I can't do this...' or 'But some situations are more complicated..'. For the second part, the 'if' makes it conditional because this example is about something that could happen.

But in someConsider a situations where, for example, youwe meet overseas and you asked me where I wasam from. Consider a situation where, for example, we meet overseas and you ask me where I am from.

To me, hypotheticals that are not strictly tied to the past sound better when posed in present tense.

If I simply said I am from China, it would not be enough because China has a special history and has a few different parts known as Taiwan (the ccpCCP thinks so), Hong Kong, Macao and Mmainland China. If I simply said I am from China, it would not be enough because China has a special history and has a few different parts known as Taiwan (the CCP thinks so), Hong Kong, Macao and mainland China.

CCP needs capital as it is a name. Try to be consistent with whether the 'm' in mainland China is capitalised or not. I think both are ok but it is good to be consistent. I feel like this sentence and the second part of the previous one should be joined together for clarity: 'For example, if we were to meet overseas and you asked me where I was from, simply saying I am from China would not be enough because China has a special history and has a few different parts.'

If I simply saidy that I am from China, ithat would not be enough because China has adue to China’s special history and. It has a few different parts known as Taiwan (the ccp thinks soaccording to the CCP), Hong Kong, Macao, and Mmainland China. If I simply say that I am from China, that would not be enough due to China’s special history. It has a few different parts known as Taiwan (according to the CCP), Hong Kong, Macao, and mainland China.

So, people who are from mainland China brarely say the term "“mainland China",”; they simply say “China”. So, people who are from mainland China rarely say “mainland China”; they simply say “China”.

When you are referencing what someone did or would say, you should use quotation marks.

When they refer to Hainan island, they don't say "mainland China", they simply say Hainan or Hainan iIsland. When they refer to Hainan island, they don't say "mainland China", they simply say Hainan or Hainan Island.

The 'I' in island needs to be capitalised because it is part of a name.

When they refer to Hainan iIsland, they don'’t say "“mainland China",”; they simply say “Hainan” or “Hainan iIsland”. When they refer to Hainan Island, they don’t say “mainland China”; they simply say “Hainan” or “Hainan Island”.

When connecting two complete sentences, you should use a semicolon ; .
