Cultural Differences

Guinea Bissau is a small country in Africa. Embalo said that his country is almost the same size as Pekanbaru city. He came to Indonesia to study and received some culture shocks during his time here.

(Instead of listing your points, I encourage you to put your statements in a paragraph form. Instead of using numbers, spell them out. For example, use the word "first" instead of 1.)
1. Of course, different cultures have their own food that is associated with their native region. In Guinea they eat rice, chicken and other foods, and the way they cook is different. He deals with it by bring some breads in the market for almost two weeks and didn’t eat rice. (In this last sentance I suggest saying something along the lines of "Not being comfortable with eating rice as offten as others around him, he substituted his rice for bread.") 
2. In Guinea there will not find somebody who put someone hand in your head (hand?). They just have a shake hand. He said people
Coping with Culture Shock
He said that he will not do anything without asking first. He doesn’t take his own initiative, because he knows Indonesia and Guinea have a different rule in.

(this section confuses me. Would you mind giving me a further explanation on what you want to say?)

Thailand is similar culture like Indonesia. When coming to Indonesia to study, Asma said that there are some culture shocks (Try to avoid the word "shock". It seems over used. Try using "differences" instead.) the first time she came to Indonesia.
1. Foods in Indonesia and Thailand are very simular, they eat some spicy, sweet and sour foods, but the first time they came to Indonesia they just bought some foods in a foods stall.
2. Thailand has a small Muslim populaton, but they are more religious than most Muslim in Indonesia. Shaking hand between man and women in Thailand is not common for a Muslim, but in Indonesia they find that most Muslim people can do it.
3.It’s hard to distinguish Muslim women in Indonesia, because some (some or most?) Muslim women do not wear a hijab. In Thailand all (all or most? using the word "all" seems like a very strong statment) muslim women wear a hijab.
4.In Thailand it’s easy to find a trash can, because almost everyplace has it’s own trash can. (try compairing this to Indonesia inorder to add more detail, rather than just a basic statement.)
