Introduce myself

Hello everybody! I'm Hang. I'm from Danang, a coastal city in central Vietnam. My hometown is well-known with a lot ot beautiful beaches and other tourist attractions such as (the?) Marble mountains, Ba Na hills, Son Tra peninsuline, and so on. The city symbol is 7 bridges across the Han river, in which, the Dragon bridge is reprensented for rapid development of Danang city.

[Great! Just a few commas and uses of "the" here and there. Your hometown sounds lovely!]
