When needs, people's behavior and speech are beautiful:

    When needs, people's behavior and speech are beautiful:

When needs, people's usage and language change according to their actual purpose or position.

    People use sincere and beautiful language when necessary to influence others or for their own benefit.

However, this behavior is not the result of sincerity - it is just a policy.

    People change their language and behavior according to their circumstances - this has a benefit as well: changing one's position helps one achieve one's goals and saves many from danger.

Many people change their behavior and nature for personal or social reasons.

    When we ask for help from others, this behavior or language changes, which may benefit them socially or lead to the accomplishment of their tasks.

There are many people who present themselves in a very beautiful way according to the situation and need.

    If someone is in a good condition and does not need anything, then their behavior or nature takes on a rather rough appearance.

Again, that person uses polite or beautiful language when necessary or in danger.

    This is when people use their behavior and language beautifully when needs.
