In order to avoid any misunderstanding from happen in the foreign country, it is better to learn about them before hand. At least we have something we know, and we've prepared about it. As for example, in Africa, there are a few cultural values that we need to know. For your information, it is rude to pointing at something or someone using index finger. "Different ethnic groups have different ways of pointing, but the method I usually employ is poking my chin in the right direction and widening my eyes", says Mark Wiens, (March 28, 2011). And you are also not allowed to point your foot sole toward others as it it the dirtiest part of your body. In Japan, it is important to know that there is no tipping given.

Then, you need to take of your shoes at the entrance to all homes and put it in the shoe rack. Usually they provide slippers for indoor but remember do not wear slippers when you are at tatami mat. "It is extremely bad form, for example, to reenter the main room of a house wearing slippers that have been running across dirty linoleum". (Wright, T. May 27, 2008)
