Law of Demeter (LoD) is also called Least Knowledge Principle (LKP), which means that an object should know as little as possible about other objects. In other words, a module or object should interact with other entities as little as possible, making the system functional modules relatively independent, so that when a module is modified, the fewer modules will be affected and the easier it will be to expand.看过这小说的人都会知道，小说开篇是邀月在向江枫夫妇复仇，哪怕江枫夫妇死后，邀月依旧要向他们的孩子复仇，让江枫和花月奴的孩子兄弟相残，以报心中之恨。A brilliant scientist is plucked out of the company lab and sent to India to sell the genetically modified rice she created - which she doesn't realize will destroy the farmers she thinks she's helping.Set Critical Hit Rate 12%In an interview with the parents of Jiang Yang's expected primary school students, the students of the practice team heard a completely different voice from the school: the teacher's qualification was low, the teaching was not responsible, the children were allowed to cheat in exams in order to achieve results, the school had potential safety hazards, and junior high schools were set up at random...

The classification method following this principle is called lineage classification. The representative of pedigree classification is "branch systematics". It advocates that the branches in evolution should be taken as the criteria for identifying and distinguishing classification units and the basis for determining the pedigree relationship of each classification unit. The so-called co-ancestral proximity (similar to a group of people being a grandfather) is used to measure the genetic relationship between different taxa and determine their position in the pedigree. The classification system finally established is an evolutionary pedigree reflecting the history of phylogeny, which is a deeper description of biological relationship. In other words, the basic principle of pedigree classification is that the classification system conforms to the evolutionary pedigree. Pedigree classification is only applicable to organisms and cannot be used for abiotic classification.
