how to establish and maintain a happy marriage

Mutual understanding is crital to the sucsess of marriage. As a saying goes:Marriage is the grave for love.'To a certain extent, it has some point in it, because love in most case is romantic and the lover only see the bright side of his or her counterpart,but the marriage invovles more vulgar things. During the daily life, you not only discover his or her bright side,you may also be reluctant to find sometimes he or she offensive to you. Therefore, mutual understanding is pretty important to maintain a good marriage. Without it, the couples will only complain each other when confronted with conflicts between them. As time goes by and the tention exists, more often than not, the marriage will eventually fall collapsed. So the most and foremost thing that a couple should keep in mind is that the precious love that bind them together. If not for that, how could they get to know and fall in with each other?
One must learn to treasure what one has had.

To como to an conclusion, I believe the mutual understanding is the most vital thing in maintaining a successful marriage.
