Colin Wu reminds: Regarding PI, if you still want to occasionally return to the mainland, it is advisable for everyone not to report or get involved.

PI has already been classified as a crime in the country, with related descriptions as shown: Pi currency, with the English name 'Pi Network', abbreviated as 'π currency'. The 'π currency' claims to be a smartphone blockchain public welfare project launched by a PhD from Stanford University, allowing for free mining with zero cost through mobile phones, and is about to become the next Bitcoin. Many criminals are using 'π currency', claiming that you can mine for free with simple operations by just downloading an app on your phone, and they conduct lectures for older adults to expand their victim group under the pretense of 'referral rewards' for developing subordinates, selling users' personal information, and defrauding elderly pensions.

Colin Wu: Recently, a very reliable friend was directly caught in ocean fishing because their product was used by a pyramid scheme group. The associated industrial chain of pyramid schemes is a target of strict crackdowns. Everyone should have some legal knowledge. Just because something hasn't happened doesn't mean it won't; if it happens once, it could be a disaster for the whole family.
