It is basically a clone of L&P.
L&P was introduced to Shanghai (and Hong Kong) by the British way back in the 19th C and the locals developed a taste for the stuff. It wasn't long before they decoded the recipe and started producing it locally.
It doesn't contain soy.
The Chinese is slightly more informative, adding dried chilli, onion, mustard seeds, tangerine peel, cape jasmine and bamboo shoot to the list.
