According to @hkdl_of_fantasy (a twitter account not associated with the Walt Disney Company), Hong Kong Disneyland has begun Cast Member soft openings to train on the new safety procedures that have been put in place to keep guests and Cast Members safe when the park reopens.
The cast member soft opening is following in the footsteps of Shanghai. They also tested several new procedures with their Cast Members, in the weeks leading up to its reopening.

According to the twitter page, the soft openings will begin on May 19th and run through May 21st, assuming everything works out. We can expect an official reopening date somewhere around the 21st, after Disney has assessed how the soft opening went.
