He need not look any further than his own family however. A native Shanghainese, Wu's father grew up in Shanghai at that time: "I asked my father about life in that era, and looked through all the old photos. That way, I got to know my family better."
Additionally Wu says costarring with Mainland actor Liu Ye and Taiwanese actor Chang Chen was critical in his decision to join the cast of 'Blood Brothers': “What attracted me the most was the chance to work with actors who are about my age and have similar experiences as me. That’s why before I agreed, I made sure that the other two were on board first."
