(Dimsun Daily) - 17th January 2026 – (Hong Kong) Johnny Tang Siu-jue, son of late Cantonese opera legend Sun Ma Sze Tsang, has long been a familiar face in Hong Kong’s entertainment scene.
Beyond show business, his fortune—and how far it stretches—remains a talking point, especially given his well-known arrangement of maintaining relationships with three girlfriends.
Public fascination centres on a widely circulated claim that Tang inherited about HK$1.5 billion after a legal battle concluded in 2006, then “parked” the funds in bank deposits. Using a conservative back-of-the-envelope estimate based on Hong Kong’s average deposit rates over the past two decades—roughly 2.2%—a simple interest scenario suggests the sum could generate around HK$330 million in interest per decade, or approximately HK$666 million over 20 years. That equates to about HK$33 million a year, or roughly HK$2.4 million per month available for spending.
Viral posts touting an eye-popping HK$1.7 billion in interest alone are highly dubious. Even with compounding, the numbers don’t convincingly reach that figure given long stretches of low bank rates; a plausible compound-interest outcome might land closer to HK$827 million over 20 years. Still, the monthly passive income implied by a HK$1.5 billion principal—well over HK$1 million on average—would comfortably cover the reported outgoings tied to his trio of partners, even without acting gigs, investing, property buys, or business ventures.
It is worth noting that the exact size of Tang’s inheritance has never been publicly confirmed; HK$1.5 billion is best treated as an estimate rather than a verified figure. Yet the arithmetic illustrates why the star is often cited as one of the city’s most financially insulated second‑generation celebrities: even modest yields on a nine‑figure nest egg can sustain a seven‑figure monthly lifestyle year after year.
