Problem: Ludendorff was born on 9 April 1865 in Kruszewnia near Posen, Province of Posen, Kingdom of Prussia (now Poznan County, Poland), the third of six children of August Wilhelm Ludendorff (1833-1905). His father was descended from Pomeranian merchants who had achieved the prestigious status of Junker. Erich's mother, Klara Jeanette Henriette von Tempelhoff (1840-1914), was the daughter of the noble but impoverished Friedrich August Napoleon von Tempelhoff (1804-1868) and his wife Jeannette Wilhelmine von Dziembowska (1816-1854), who came from a Germanized Polish landed family on the side of her father Stephan von Dziembowski (1779-1859). Through Dziembowski's wife Johanna Wilhelmine von Unruh (1793-1862), Erich was a remote descendant of the Counts of Donhoff, the Dukes of Duchy of Liegnitz and Duchy of Brieg and the Marquesses and Electors of Brandenburg.

In the West in 1916 the Germans attacked unsuccessfully at Verdun and soon were reeling under British and French blows along the Somme. Ludendorff's friends at OHL, led by Max Bauer, lobbied for him relentlessly. The balance was tipped when Romania entered the war, thrusting into Hungary. Falkenhayn was replaced as Chief of the General Staff by Field Marshal Hindenburg on 29 August 1916. Ludendorff was his chief of staff as first Quartermaster general, with the stipulation that he would have joint responsibility. He was promoted to General of the Infantry. Chancellor Bethmann-Hollweg warned the War Cabinet: "You don't know Ludendorff, who is only great at a time of success. If things go badly he loses his nerve." Their first concern was the sizable Romanian Army, so troops sent from the Western Front checked Romanian and Russian incursions into Hungary. Then Romania was invaded from the south by German, Austro-Hungarian, Bulgarian, and Ottoman troops commanded by August von Mackensen and from the north by a German and Austro-Hungarian army commanded by Falkenhayn. Bucharest fell in December 1916. According to Mackensen, Ludendorff's distant management consisted of "floods of telegrams, as superfluous as they were offensive." When sure that the Romanians would be defeated OHL moved west, retaining the previous staff except for the operations officer, blamed for Verdun. They toured the Western Front meeting --and evaluating-- commanders, learning about their problems and soliciting their opinions. At each meeting Ludendorff did most of the commander's talking. There would be no further attacks at Verdun and the Somme would be defended by revised tactics that exposed fewer men to British shells. A new backup defensive line would be built, like the one they had constructed in the east. The Allies called the new fortifications the Hindenburg Line. The German goal was victory, which they defined as a Germany with extended borders that could be more easily defended in the next war. Hindenburg was given titular command over all of the forces of the Central Powers. Ludendorff's hand was everywhere. Every day he was on the telephone with the staffs of their armies and the Army was deluged with "Ludendorff's paper barrage" of orders, instructions and demands for information. His finger extended into every aspect of the German war effort. He issued the two daily communiques, and often met with the newspaper and newsreel reporters. Before long the public idolized him as their Army's brain.

Problem: A Hakka, Kate Tsui was born and raised in Hong Kong. Her father works in logistics, and while her mother is now a homemaker, she was a dancer when she was younger. Tsui also has an older sister, who is married with two kids. As of 2014, Tsui has expressed that with the exception of herself, her entire immediate family now resides in Taiwan.

Aside from her development in television acting, Tsui also experienced success in developing her career in the film industry. In 2007, through a series of auditions, Tsui was cast as the female lead, alongside A-list actors Tony Leung Ka-fai and Simon Yam, in Eye in the Sky, which is a film produced by Johnnie To and directed by Yau Nai-hoi. With her performance in the film, Eye in the Sky was praised by professional Hong Kong film critic, Sek Kei, as the best Hong Kong film in the first half of 2007. The film was subsequently entered into the Berlin International Film Festival, as well as the Shanghai International Film Festival. Through her performance in the film, Tsui was widely acclaimed to be talented in acting and a rising actress worth looking out for. With her performance in Eye in the Sky, Tsui earned the Best Newcomer - Gold Award from Hong Kong Film Directors' Guild 2007, as well as Hong Kong Film Award for Best New Performer from the 27th Hong Kong Film Awards, held in 2008. The latter is a particularly outstanding achievement, for Tsui is, so far, the only individual to have received a Hong Kong Film Award, while being fully contracted by TVB, since Anita Yuen, who coincidentally is also a Miss Hong Kong pageant winner, won the same award back in 1993. Professional Taiwanese film critic, Mai Ruoyu, had openly criticized the Golden Horse Film Festival and Awards, a film festival and awards ceremony held in Taiwan, for excluding Tsui and her performance in Eye in the Sky from a nomination in the Best New Performer category. He had further praised that Tsui has the most potential and talent in acting among all of TVB's Miss Hong Kong-turned-actresses, since Maggie Cheung.
