In ancient times, matchmaking paid great attention to one's "Birthday," and even if Zhulan raised Wu Ning exceptionally well, few families would choose Wu Ning as a daughter-in-law.
Zhulan was not in a hurry, though. Wu Ning was still young this year, and she mainly wanted Wu Ning to adapt first and then slowly have Wu Ning manage the household with Xue Han.
In fact, before Wu Ning arrived, Zhulan had already sent a letter to her sister-in-law, inquiring whether her youngest nephew, Wu Hai, had been betrothed and casually mentioning Wu Ning's situation. Although she didn't make it explicit, her sister-in-law, being the smart person she was, understood and subtly rejected the proposal after seeing the girl.
For the Yang family, being a military general's household, they particularly avoided matches that might bring bad luck, not to mention the situation with Wu Dong and the serious injuries Wu He had suffered. Zhulan wasn't surprised by her sister-in-law's rejection.
