I Was Blind and Recognized the Wrong Person, How Could You Make the Mistake Right?

(Mistaken admission + Beautiful and powerful but miserable male protagonist (puppy with low self-esteem) + Love career and emotional novice female protagonist + Era + Traveling through the 70s + Inner Mongolia + Large level plug-in + Surveying and mapping military doctor + Marriage first, love later) Jiang Yi passed through a book and became a vicious real daughter. The real daughter returned to her parents' house and was not taken seriously. After competing with the heroine for a man, she died tragically. Jiang Yi knew the plot and went to Inner Mongolia with the package to marry his baby partner. (The heroine is a real daughter in life, but she is not a real daughter in the book) Unexpectedly, the baby's biological partner disliked her for being a country girl and not worthy of his status as a cadre's son, so she found someone to replace her and marry Jiang Yi. Jiang Yi was blind and didn't recognize it. He actually received the certificate from Fu Xiangdong. The matter was revealed just after receiving the certificate, and Jiang Yi was dumbfounded. What to do? I can't go home, and I married the wrong person again. Jiang Yi pinched her waist and glared at the cold-faced man in front of her, "We agreed, we just agreed to get married! We will part ways in two years." Later, Jiang Yi devoted himself to the national surveying and mapping undertaking. Fu Xiangdong's life experience was miserable, and his world was dark and dull. Jiang Yi was like a bright moon, beautiful and shining. He treated her with the most devout love as she treated this land. Jiang Yi: "Love makes people soft, Fu Xiangdong, I slowly begin to feel sorry for you."
