In real life, China's income tax is divided into enterprise income tax, foreign-invested enterprises or foreign-invested enterprises income tax and personal income tax. For these three types of income tax, each is calculated in a different way. Personal income tax has a personal income tax calculation method, while enterprise income tax has its corresponding calculation method. If we do not adopt the policy mode to realize such a requirement, we will define an income tax class, which has an attribute to identify the type of income tax and a CalculateTax () method to calculate the tax. In this method, we need to judge the tax type and calculate the income tax for different tax types through if-else statements. Such an implementation can indeed solve this scenario, but such a design is not conducive to expansion. If the system needs to add an income tax in the later period, it has to go back and modify the CalculateTax method to add an additional judgment statement, which clearly violates the principle of "open-closed". At this time, we can consider using the strategic mode to solve this problem. Since the tax method is the changing part of this scenario, we can naturally think of abstracting the tax method at this time, which is also the essence of the implementation of the strategic mode.

ITV’s six part factual drama, White House Farm, produced by New Pictures revolves around one fateful night in August 1985 when five members of the same family were murdered at an Essex farmhouse; Sheila Caffell, her twin six-year-old sons, Daniel and Nicholas, and her parents, Nevill and June Bamber. The series will seek to provide fresh insight into this family tragedy and the contested accounts of the events that took place at White House Farm. Based on extensive research, interviews and published accounts including, ‘The Murders at White House Farm’ by Carol Ann Lee with additional material from ‘In Search of The Rainbow’s End’ by Colin Caffell, husband of Sheila and father to Daniel and Nicholas Caffell. Essex Police initially believed that Sheila, who had mental health problems, had murdered her own family before turning the gun on herself. But Detective Sergeant Stan Jones had doubts about the murder-suicide theory, and about Sheila’s brother Jeremy Bamber, who first called the police to the farm. Eventually it was Jeremy Bamber who was charged and convicted of the murders of his own parents, sister and nephews. Bamber is currently serving life imprisonment without the possibility of parole. He is one of the few prisoners in the UK subject to a whole-life order. Bamber still maintains his innocence.
