What is goverment?I think chief minister is called goverment. Is it right? Actually sometimes any Minister does anything for public, then it is...

The government of a country is the people who are in
control of that country at a particular time.  The term generally refers to both the
elected parts of the government (the legislature and the executive, for example) and the
unelected civil servants who carry out the laws that are made by the elected
officials.

The term "government" can also refer to the
party that is in power in a parliamentary system.  For example, we refer to the current
"coalition government" in Great Britain.  In this case, we are still talking about the
people who are in control of the country (as discussed above) but we are also talking
specifically about the party that is in power.

Overall,
then, both of the things you are referring to are part of government.  The chief
minister or prime minister is the leader of the government, but all of the other
ministers (and their subordinate civil servants) are part of the government
too.
