Here is an interesting interview with Zhang Zuolin (1873 – 1928), the Chinese warlord who oversaw Manchuria and much of North China during the last fifteen years of his life. The article was written by the old China-based correspondent Randall Gould.
"Marshall Zhang, drawn to Peking from his native Mukden 'to cooperate with the foreign ministers in saving China from Bolshevism', talks in terms of nations but continues to think in terms of provinces. Anyone who has spent half an hour with him knows this. The Strong Man of Mukden has improved his propaganda vocabulary but he is using the same old brain - shrewd, keen, but sharply limited."
