According to an article by Caijing magazine, the computer that Qian Zhimin took with him when he fled contained a built-in cryptocurrency wallet, which became the source from which funds were later dispersed into multiple crypto wallets. After several searches by UK police, multiple phones, computers, and USB drives were seized. One of the USB drives contained photos of pages from Qian Zhimin's notebook, and it is suspected that the relevant pages from the notebook were torn out before the police confiscated it. The photos recorded the boot password for the black computer and several mnemonic phrases, such as "number + love," along with some hints about the numbers. It was precisely this key information that made the recovery of the Bitcoin possible.
