Please briefly describe the "marriage of gold and jade" and "alliance of wood and stone" in A Dream of Red Mansions.

"Good marriage" refers to the marriage between Baoyu and Baochai: gold-Xue Baochai, jade-Jia Baoyu. In A Dream of Red Mansions, Xue Baochai wears a golden lock around her neck, which is said to be given by a donkey-headed monk, saying that she can only be worthy of someone who meets jade in the future. Jade refers to Jia Baoyu's "psychic Baoyu".

"Mu Shi Qian Meng" refers to the marriage between Baoyu and Daiyu; Stone refers to the stone left by the goddess of mending heaven, which later turned into psychic Baoyu. Its predecessor was the messenger who greeted the gods, and irrigated the crimson pearl fairy grass all day, and the fairy grass was cultivated into Lin Daiyu. In order to repay the angel for his irrigation, she repaid him with tears all her life, which is why Lin Daiyu loves to cry so much!
