Thailand beaches

I would like to visit the beaches of Thailand because they are beautiful, however I would like to visit more is the city of Bangkok because it is a very beautiful city that I was told that it was on of the coolest city in Thailand. Bangkok, one of the better known countries in the world. The average temperature  stays the same throughout the summer and winter as an average 80 degrees. It would be interesting to see the things that they have there. There are 50 districts in Bangkok. In Thailand more than a small amount of the population speaks Chinese. Would you visit Thailand? I have a hard time with good work choice.
