I would be very curious to know if English is spoken throughout the park in Hong Kong.
Yes, English is spoken throughout the park. Hong Kong was once a British territory, and the cast members speak both English and Chinese.
The Jungle Cruise has three lines, and you choose the one you want so that the skipper will speak your language (English, Mandarin, or Cantonese). See the photo below.
The safety spiels and signs are in all three languages.
The Stitch Encounter show (very similar to Turtle Talk) is divided up during the day according to language - the morning was Chinese and then it was switched to English in the afternoon.
They had a stage show called Golden Mickey's that was in Chinese but had large screens with English subtitles.
Mickey's Philharmonic was identical to WDW and only in English.
