SOYA beans - tiny, round, and whitish-yellow - may not seem like the stuff fortunes are made of. But for Lo Kwee-seong, that is just what they became when he turned a backstreet operation making soya milk drinks into a multi-billion dollar stalwart of Hong Kong life - the ubiquitous Vitasoy.
When Mr Lo died last May at 85, the company had profits attributable to shareholders of $122 million and turnover of $1.25 billion for the 1994-95 financial year.
Mr Lo had become a Commander of the British Empire, had a fine collection of Chinese art, contributed substantially to the Hong Kong Museum of Teaware and had made millions from his famous soya beverage.
After his official retirement from Vitasoy - set up as the Hong Kong Bean Product Co - at the end of 1993, he weathered some controversy over a huge $45 million payoff he received during the company's public flotation in 1994.
But the product itself retained its image of wholesome goodness and efficient production.
Now, however, the company is suffering a severe bout of indigestion that some management experts reckon will take months - or even years - to shake off.
Problems with sour milk and production faults have dogged the company at both its Tuen Mun and Shenzhen plants for the past three months.
