In the shadowy era of 1930s Shanghai, when foreign concessions turned the Bund into a nest of espionage, a shadowy operative compiled the Great Shanghai Ledger—a forbidden register naming collaborator
The Bund — Uncover the Great Ledger
You are an independent financial investigator, newly arrived in Shanghai in 1929, tasked with uncovering the secrets behind the city's colonial fortunes.
You step into the shoes of Victor
Dive into the golden age of colonial Shanghai where European tycoons built Asia's greatest commercial port between 1920 and 1930.
The story that haunts this land
The Peace Hotel rises before you like an Art Deco lighthouse from 1929, former Cathay Hotel of the Sassoon brothers who revolutionized Asian hospitality. Victor Sassoon invested a fortune to create Shanghai's first modern palace, attracting Charlie Chaplin in 1947 and the Duke Ellington Orchestra in 1960. Renovated in 2010 for 1.7 billion RMB, this monument at 20 Nanjing East Road keeps within its walls the secrets of negotiations that shaped modern Chinese economy. Your mission begins here: decrypt clues hidden in its facade's geometric patterns to locate the first register.
The HSBC Building impresses you with its 8 Corinthian columns of 20 meters, erected in 1923 by Palmer & Turner for 10 million silver taels. This 53-meter banking cathedral housed the Far East's largest vault, a 2000 m² underground labyrinth where capital from across the British Empire in Asia transited. Hongkong and Shanghai Banking Corporation centralized financial flows between London and Hong Kong, transforming Shanghai into global trade's hub. The neo-classical walls still bear traces of secret transactions that financed China's industrialization.
Shanghai Customs House raises its 80-meter tower since 1927, crowned with a 9-meter clock inspired by Big Ben. This neo-classical giant chimed merchant ship arrivals since 1928, its England-imported mechanism rhythming Asia's economic pulse. Until 1996, this building controlled all Shanghai customs flows, recording in its archives the fortunes transiting through the port. Each bell strike marked colossal capital entry or exit, creating the first Sino-European multinationals.
Nanjing East Road unfolds its 1.03 km of cobblestones since 1999, but this pedestrian artery follows 19th-century international concessions' layout. One million pedestrians daily walk this route that once connected European trading posts to Chinese quarters, creating Asia's first commercial melting pot. Accessible by metro lines 2 and 10, this avenue keeps memory of first Sino-Western exchanges that transformed a fishing village into a 24-million-inhabitant metropolis. Modern facades hide foundations of China's first European stores.
Your Bund journey reveals how 52 historical buildings from 1890-1930 redesigned the world economy from this 1.6 km Huangpu quay. Since 1990's night illuminations, these stone witnesses tell the first globalization's story, when Shanghai concentrated 80% of Sino-Western trade. You leave with intimate understanding of this urban revolution that inspired all modern Asian metropolises, from Hong Kong to Singapore. The reconstructed Great Register reveals how colonial architecture generated the Chinese economic miracle.
