Since someone went, of course, the gift money can't be too little. Especially for Zhao Xiaolan as an elder, who is the bride's grandmother's younger sister, the gift money especially can't be too little.
However, for Chen Feng's family to get back the gift money they sent, it seems like they'll have to wait until Chen Feng's two nieces get married, which is at least ten years from now.
Of course, it could also be when Chen Feng remarries and throws a banquet, they'd send him a red envelope. But Chen Feng has no such plan.
Even if he does remarry in the future, he wouldn't voluntarily send invitations to his cousins, at most just call a few male cousins, as per the generally accepted custom and tradition over there.
[Alright then. You handle my gift money. Same as my elder brother's.]
[Okay. Are you really not coming back?]
Zhao Xiaolan obviously wants her son to come home.
