How do I deal with my wife's relatives and friends (most are from Shanghai) showering us with gifts I appreciate it but feel so uncomfortable.

我该如何应对妻子的亲友(大多是上海人)送来的大量礼物?我很感激,但实在感到不自在。

My wife's family is super rich, most of them live in Shanghai, every time they visit, they hand her and me (one each) one of those red envelopes. Sometimes with 50-100 100€ bills, just willy nilly.

我妻子的家族超有钱,他们大多住在上海,每次来访时,都会递给我和妻子(每人一个)一个红色信封。有时里面装着 50 到 100 张 100 欧元的钞票,就这么随意地塞给我们。

We always refuse (my wife says you have to refuse as hard as you can and then let them come out on top. If you truly refuse it means you think they cant afford it).

我们总是婉拒(我妻子说,你必须尽最大努力拒绝,然后盛情难却。如果你真的拒绝,意味着你认为他们负担不起)。

yes, this sounds like a huge first world problem but how do I come to terms with it

是的,这听起来像是第一世界的大问题,但我该如何接受这种情况呢?

My wife was out with her mom and her mom's best friend, while the friend was visiting Berlin, and they just bought ME an expensive watch, which I NEVER would have accepted.

妻子陪她妈妈和妈妈最好的朋友在柏林逛街时,竟然给我买了一块昂贵的手表——这礼物我绝对不愿收下。

I truly dont know how to deal with this. Before my marriage to my wife I had never been gifted anything worth more than 500€ at most.

我真的不知该如何应对。在和妻子结婚前,我收到过最贵的礼物也不超过 500 欧元。

Nowadays its crazy. I truly do not want to accept these things, but my wife says it would be super insulting to say no.

如今这情况太疯狂了。我实在不想接受这些东西,但妻子说拒绝会非常失礼。

How do I come to terms with the fact that gift giving is super different in Chinese culture

与中国文化中的送礼习俗差异如此之大,我该如何调整心态去适应?
