Can you use debit card in Hong Kong?

Can you clarify for me, please, about the use of debit cards in Hong Kong? I'm curious to know if debit cards are widely accepted as a form of payment in various establishments, such as restaurants, retail stores, and even for online transactions. Are there any specific debit card networks that are more popular or widely accepted in the region? Additionally, are there any restrictions or fees associated with using a debit card in Hong Kong that a consumer should be aware of? I would appreciate your insights on this matter.
