Last week I heard a radio interview with Ingrid Yeung, I was quite surprised that her spoken English isn't that fluent as she is an English Ph.D. from HKU. In recent years among many Hong Kong senior officials, Carrie speaks the best English and can express herself well. It's a good opportunity to learn from her not just her English presentation skills, but also some words that we also use in current affairs.

NPC --> National People's Congress
NPCSC --> National People's Congress Standing Committee
GBA--> Greater Bay Area
SAR --> ??
ETO --> ??
Guess it and also tell me the Chinese translations.
