 Another feature worth noting is the characterisation of historical figures.Sun Yat-sen, Soong Ching-ling and Zhang Xueliang are portrayed as noble individuals while Chiang Kai-shek and Soong Mei-ling are portrayed less favourably.A reason for this may be that filming took place in Beijing, where the Chinese government imposed rules on the portrayal of controversial figures such as Chiang Kai-shek.
