Clever idea:
China's "descendants" are sold to foreigners at the price of 250 yuan. This ingenious design is worth pondering. "Descendants" means more than just the pair of walnuts.
The comparison between Fu's walnut income, walnut treatment and walnut loss in antique shops is also thought-provoking: if you want to give walnuts to Fu, Fu must give him two yuan, which is said to be a great advantage of him, but the cultural relics shop was obtained from Fu's family during the Cultural Revolution; Fu loves these walnuts as much as he loves his own life. He made two small cotton wool pockets, put two walnuts in them and took them with him. Antique shops throw away small pockets and sell them to foreigners. Fu often visited antique shops after Wen Ge, hoping to see the pair of walnuts like looking for a needle in a haystack, but the shop assistant treated them coldly and sold them to foreigners.
