The most impressive is certainly "deep love", and the most classic line is "open the door ah open the door ah don't hide in the inside without making a sound, I know you are at home".
When I saw this scene when I was small, I didn't really feel much. It turned out to be a popular flirtation stunt now, and Auntie Xue herself loved the setting.
After the September 18th Incident, Lu Zhenhua (Kou Zhenhai), a local warlord from the northeast, fled to Shanghai with his family and settled in the French Concession. His Ninth Aunt Xueqin (Wang Lin), who is bossy and domineering, expels his Eighth Mistress Wenpei (Xu Xing), his mother and daughter, and Lieutenant Li (Cao Qiu Gen) from the Lu family. The two families are temporarily deprived of their financial resources and live in poverty and embarrassment. Wenpei's daughter, Yi Ping (Zhao Wei), goes to her father's door to ask for money to support her, and is whipped by her father after a confrontation with Xueqin, setting her sights on revenge.
To make ends meet, Lieutenant Li has to work as a yellow cab driver. One day, his daughter Ke Yun (Xu Lu) falls ill and he comes to Wen Pei for help. However, Wenpei has difficulty helping the Li family. Seeing this state of affairs, Yi Ping decides to go to the Shanghai Ballroom to work as a singer without her mother's knowledge. At the ballroom, she befriends a filing reporter, Shu Heng (Leo Ku). When she learns that Shu Heng is the boyfriend of Ru Ping (Ruby Lin), the daughter of the 9th Aunt, she is tempted to take over the love of her life. Unexpectedly in the relationship, Yi-Ping fell into the love net, and he fell in love with him sincerely.
