Real estate agent in Da Nang looking for cultural ‚do’ and ‚donts’

Excited to accept job in a real estate firm in Da Nang. Will be working with a team of 20 Viet realtors as well as few foreigners.

Looking for any tips on handling Viet clients but also native colleagues. Any cultural ‚things’ I should be aware of?

My management background comes from US but I am originally from Europe. My communication style is very direct and blunt - pretty sure it will be an issue. Already experienced working with S Indians (Chennai).

Thankful for any advice and suggestions
