My Chinese husband and I have been married for over 11 year now. Most arguments/difficulties we've had (well, apart from those caused by me ha ha) have arisen from what I call the Three Fs - Family, Face, Finance! His take on these is so different from mine that it is inevitable that we are going to argue about them.
His relationships and ties to his family and friends are VERY different from the ties/relationships between me and my family/friends. Some of the tension is related to finance - as far as I see it, for Chinese people (or at least my husband), being family or friends means that you should be willing to share everything including money. So when his useless, deadbeat friend is in town my husband has to take him for dinner and drinks, paying for everything, and also lends him a few hundred RMB (I say lend but the money never comes back). Now we can afford this, but in the past we couldn't yet he would still do it. Some of it comes down to my husband being a very proud man so it is important to him that he does what is expected of him. I am a realist - if someone genuinely needs my help, and I can do so without it impacting my kids, I will help however I can but if someone is a deadbeat, why should I fund that!
Another example - when I was in the UK last summer my husband phoned and asked me to buy him a new leather wallet and belt. I knew he had just bought these items for himself so asked why he needed yet more. His reply - when he was home his friend admired his belt and wallet and asked to have them, so he had given them to him! This is just plain weird to me - if I really liked something a friend owned, I might ask them where they got it and perhaps enlist them to help me buy something similar, but I would never ask them to give it to me.
