　　Different from other provinces,Hainan is the second largest ocean island and the smallest land province in China.Although scenery in Hainan lacks the grandness of the Great Wall and the mystery of the Terra-Cotta Warriors,its natural beauty has gained a good reputation among the visitors and has been widely known around the world.People call it "the Oriental Hawaii".
　　Hainan is located at south end of China,and occupies an area of 35,000 square kilometers (13,510 square miles).Its administrative regions are Hainan Island,Xisha archipelago,Zhongsha archipelago and Nansha archipelago.Its neighboring countries are Philippines towards the east,Malaysia and Brunei towards the south,Indonesia (Natuna Islands) towards the southwest,and Vietnam towards the west.The surrounding sea area totals 2,000,000 square kilometers (772,000 square miles).Due to the mild climate and favorable environment,Hainan is regarded as a long life island.The young often travel to Hainan seeking a return to nature and the old would rather live there to enjoy their lives.Hainan now has a population of 7.11 million,among which about one million are ethnic minorities.
　　Ethnic Minority Groups
　　Tianya Haijiao,Sanya,Hainan
　　Hainan is a multinational region,and there the ethnic villages of Li and Miao are very typical.The hospitable villagers will treat you to traditional food as well as wonderful singing and dancing performances.So the Li and Miao Villages are well worth a visit in Hainan.Nowadays,Hainan cuisine is very popular all over the world,especially the fresh and delicious seafood.Furthermore,Hainan is famous for their beautiful handicrafts,like shell carvings.
　　The capital of Hainan is Haikou City.Located in northern part of the island,it is the political,economic,cultural and transportation center of the whole province.In Hainan,the cities Haikou and Sanya are where most tourists congregate.
　　When to Go
　　Hainan is an ideal place for you to be away from the cold winter.In January and February,the average temperature is 16C to 24C,and 25C to 29C is in July and August.The rainy seasons are from May to October.The best time to visit Hainan is between November and March the next year.I suggest those who are fond of swimming had better come to Hainan.It's an excellent swimming and bathing place all the year around,and far away from the crowded cities,it is your best choice for relaxation and entertainment.
　　What to See
　　Sanya is famous for its tropical beach landscapes.Tianya Haijiao and Dadonghai are two well known beaches.Just imagine that you are lying on the soft beach under beautiful sunshine or that you are walking through the coconut plantation under the blue sky.How wonderful everything is!Historical heritages such as Hairui Tomb (Hairui (1514 - 1587) who was a compassionate and popular officer during the Ming Dynasty) and Wugong Temple (Fiver Officials' Temple) in Haikou are also worth a visit.

In late November,Hainan,Sanya,warm as summer,tourists gather here to enjoy the sunshine beach.They may not know,in the near future,there will be the "Chinese Hawaii",because the fate of a possible change in Hainan,"Hainan Island,Plan International Travel" has been presented the State Department during the year may be granted.

I'm glad you come to China,first wish you good luck in the China trip!

One possible version:
Dear Jane,
I’m so happy to receive your letter and get to know you are going to visit Hainan.
If you want to have a satisfactory trip, it’s necessary to make some preparations ahead of time. First, look through some related websites to get more information about Hainan tourism. I suggest you take a train along the new East Ring Railway to enjoy the beautiful scenery. In addition, it’s hot and humid in July in Hainan, so you’d better bring some summer clothing such as T-shirts, a cap, an umbrella and so on. Remember not to miss the local food and some famous places of interest, such as Nanshan Temple and Five-finger Mountain.
In a word, I hope everything will go well and you can have great fun during your stay in Hainan.
Yours truly,
Li Hua
