Li's Field (Chinese: 李氏力場, also known as Li's force field or K.S. Field) is a tongue-in-cheek conspiracy theory in Hong Kong over the existence of a force field that repels tropical cyclones from the city.

Background
The "Li" in Li's Field refers to local business tycoon Li Ka-shing, the implied developer of the field. The basis of Li's Field rests on the way Hong Kong's government is organized. The city's Commerce and Economic Development Bureau oversees the Hong Kong Observatory,and that has led to speculations the Observatory bases its issuance of tropical cyclone warning signals on economic reasoning, instead of scientific reasoning.
In Hong Kong, schools above kindergarten level are shut down when Tropical Cyclone Signal Number 8 is issued (kindergarten classes are suspended when Signal Number 3 is issued), and all non-essential staff at a workplace are sent home. Some believe businesses have pressured the Observatory into avoiding the issuance of Typhoon Signal Number 8, in an effort to avoid economic losses.
Examples
From 2005 to 2006, and once again in 2010, the Observatory did not issue a single tropical cyclone warning above Number 3.
Typhoon Prapiroon
In 2006, Typhoon Prapiroon brought 200km/h wind to Hong Kong, overturned containers, uprooted trees, and caused many flight delays at the airport, but the Observatory did not issue Signal Number 8, remaining at the lower level Signal Number 3.
Observatory Chief Lam Chiu-ying later said the decision was based on the fact that wind speeds in Kai Tak, near the Victoria Harbour, did not reach the level required for issuing Signal Number 8. Nevertheless, humorous speculation arose that Li Ka-shing was behind the decision, in an effort to maximize productivity from his workers and prop up the economy.
Scientific reason
Media reports in 2010, citing research by the Observatory, revealed the reason behind the fewer occurrences of Signal Number 8. It is believed that an ocean temperature difference between the South China Sea and the Pacific Ocean is to blame.
Reaction From The Observatory
Former Observatory Chief Lee Boon Ying told reporters in 2010 the Observatory has always put the safety of Hong Kong residents as its first priority, and is not swayed by business or economic concerns.
Survey
In an impromptu survey conducted by Observatory Chief Shun Chi Ming at a student forum in 2014, about 20% of approximately 100 students in attendance say they believe Li's Field exists.
