The  question is :  How  can we exchange culture.   Actually,  we  can’t  physically  exchange  cultures, but  we  can discuss  the  intricacies of  different  cultures.  We  can talk of what is the  best  in particular  culture.  What  are the  specialities, traditions followed  in  cultures.  By understanding  any  culture  we  can mix up  with those  people, build  healthy relatins with them, learn excellent  aspects and make our  place  worth living.
We  should  talk to the  people  from various  countries.
