Mrs. Lu's tomb is on the mountain, a bit of a distance from the village, and the weather now is freezing, making the road quite slippery.
Song Wei almost supported Wen Wan all the way up.
Father Wen walked on the other side of Wen Wan to prevent her from suddenly falling, holding a bamboo cane in one hand and a bamboo basket in the other.
Inside the bamboo basket, there's paper money, incense sticks, and offerings, burning these for "Mrs. Lu" isn't a problem.
During their last meeting, Father Wen learned that Fanghua's husband is Lu by surname.
He quickly connected Fanghua's name possibly being fake, because back then, she told him it was Wan Niang's biological father's surname.
As for why the real surname cannot be revealed, or which surname should not be casually pronounced? Father Wen is not a brainless person; upon reflection, it's easy to guess.
Fanghua's identity is indeed nobler than he imagined, and even more constraints than he expected.
