Engagement custom in Tianjin! ! !

I don't seem to be very particular. I'm not sure. We just got engaged, that is, my parents met and sat together for dinner. Then my mother-in-law gave me the dowry money and said that I could buy whatever I wanted (of course, this is polite, because part of the dowry money is for home appliances). As for the ring, we bought it ourselves. My husband bought me a bigger one. If my mother-in-law bought it, I'm embarrassed to buy it.
