Chang Fei's son, Chang Shao-Hwai, and his wife, Weng Hsin-Yi, have been married for 12 years. Weng frequently shares family life and travels regularly to Japan, where they have also purchased property in Tokyo. Regarding the doomsday prophecy for July 5, Weng expressed that she has been asked multiple times but ultimately decided to buy a ticket for the trip.

On social media, she wrote, "I don't know how many times I've been asked about July 5. Honestly, when I bought the ticket, I wasn't thinking about anything; I'm already anxious enough without worrying about the future." However, she finally chose to visit Yamanashi Prefecture, far removed from busy areas.

Describing her travel destination, Weng said, "I found a hundred-year-old traditional house, giving a timeless feel. In this village, there's even no convenience store, away from urban hustle, and time seemed to slow down, allowing us to enjoy a very quiet day together." She also expressed her wish regarding the doomsday prophecy: "May there be no disasters, may the world be at peace, and I hope to wake up tomorrow everything is as usual."
