I would like to ask how the marriage was when the master Gui Hainian was born.

You should be lucky. Your horoscope is not bad. The problem lies in your date of birth, which is bad for your marriage. Both financial officers are good. Ren Xu and Chen Bing (in your eight characters) are rushing to the ground, and C is using God, so it is impossible to be good with God; Besides, the Ren Xu Universiade is also your canopy luck. Sewing the canopy luck is beneficial to academic research, not marriage.
