Which country should I list as my departure country on the TP form if Macau is not listed?

The user is unsure about filling out the TP (Thailand Pass) form for their trip, as Macau is not listed as a departure country. They are considering whether to list China or Hong Kong instead, noting that they will be flying from Macau to Singapore and then to Bangkok. Comments from the community suggest that Macau is technically part of China, and therefore, they should choose China. Additionally, there's a reminder that Macau is not on the quarantine exempt list, which may affect their entry into Thailand.
