There are many ways to manage face. Do it with care. If the receiving party feels that you are hypocritical, the outcome can be more harmful than good.
Praising
You may ‘give’ face to someone by praising him in front of others, especially the people that he values, such as important customers or government officials. It could also be done through presentation of token gifts, or expressing your gratitude for what he has done on occasions where people important to the receiving parties are around.
'Saving' face
You may ‘save’ someone’s face by coming to his rescue by saying something to salvage an embarrassing situation.
'Giving' face
You may ‘give’ face to someone when he seek favor from you by going out of your way to help.
'Keeping' face
You may ‘keep’ someone’s face by subtly doing something for him. For example, intentionally lose the golf game that you could easily win.
