In Chinese culture, the purpose of this traditional custom of gifting a Si Dian Jin wedding jewellery set is twofold.\
\
Firstly, it serves as a way to welcome the new daughter-in-law to her new family. The mother-in-law will present this bridal set to her daughter-in-law before their wedding day during the Guo Da Li (过大礼) ceremony.\
\
Secondly, this wedding gift is also an offering of goodwill to the wifeâ€s family for raising such an amazing woman who will now become a wife.
