give them half, take the father to one side and explain about all the expenses u have with the baby on the way and you will cough up the rest at a later date when u can afford.
OTHERWISE REFUSE TO GO, Chinese hate to loose face.
has your wife got any grasp of your finances ? or does she think that all Europeans are rich ? did she marry u for love or love of money ? put her in her place [ kindly] now otherwise these demands will continue all your married life, wise up now and take a stand.
good luck
