Chungking Express (chóng qìng sēn lín 重庆森林) was the first of Wong Kar Wai (wáng jiā wèi 王家卫)'s films to gain international plaudits but was actually made as a cinematic exercise to help him regain some perspective in the middle of editing a huge Hong Kong (xiāng gǎng 香港) epic: Ashes of Time. The film, a simple, straight forward character piece that reaches unexpected levels, rightly described as a love note to Hong Kong, tells two different and unconventional love stories connected by having cops and a fast food joint named Chungking Express. Made with a down and dirty feel which probably reflects the production itself as well as the intended style we are brought into the streets of Hong Kong and the bustling effervescence of this city as only Wong can describe, which makes it unparalleled to any other.

The Equation of Love and Death (lǐ mǐ de cāi xiǎng 李米的猜想), also called Aishichang (ài shì cháng 爱逝偿) is a 2008 Chinese dramatic film written and directed by Cao Baoping (cáo bǎo píng 曹保平) and starring Zhou Xun (zhōu xùn 周迅). The film is a Chinese Huayi Brothers (huá yì xiōng dì 华谊兄弟) and Hong Kong (xiāng gǎng 香港) co-production. It is Cao's second solo feature after 2006's Trouble Makers (jué duì qíng gǎn 绝对情感). This time, the film concentrates on small potatos: strange woman bus driver, countrified “criminals”, a serious policeman and a mysterious handsome guy. This is not a mysterious movie but a movie reflecting the simple and pure love, distressed and touched, which is just  around our daily life.
