Ineed to write an informative essay with a cultural history can some one give me some ideas? (i do like chinese culture and other asian cultures)

That's great that you've already chosen a topic. I would recommend you to brainstorm the ideas and using mind-mapping techniques extend it. The Informative Essay is the first one you will learn to write. This kind of writing explains something, tells something, or it gives directions.Revise. Then read again and revise again. Keep on improving your writing until you can be proud of it. Never turn in a rough. Supreme essay guys can help you with it. Good luck!

Chinese and Asian culture...hmmm...

-the making of the Great Wall of China

-Japan's foreign policy (Closed Country Edict of 1635) 

-effect dropping the atomic bomb over Hiroshima and Nagasaki had on Japanese society (and how Japan recovered from it, if it did at all) 

-Japan's motives for bombing Pearl Harbor 

-Affect of Westernization on Japan's modernization

- Analysis of the Ramayana (heroic epic) and how it influenced the morals, values, and ideals of Indian society for that time period as well as today

- Effects of Mongols conquering China on traditional Chinese culture 

- the Controversial Tradition of Foot-binding (its significance in history as well as its lasting effects on Chinese society and culture today) 

-the influence of Confucianism on modern Chinese culture (through the implementation of Filial Piety and other ideologies)

These are just some of the many ideas that you could use! Good luck my friend, hope this helps! :)
