What are the three or six zodiac signs of the Jockey Club's four-character poem?

The Jockey Club's four-character poem refers to the four numbers of lottery bets issued by the Hong Kong Jockey Club. "Three-six combination" refers to the combination of numbers with mantissas of three and six into a lottery ticket, which does not represent a certain zodiac sign. Zodiac refers to the animal symbols in the zodiac, including rats, cows, tigers, rabbits, dragons, snakes, horses, sheep, monkeys, chickens, dogs and pigs. In the Jockey Club lottery, the number is not necessarily related to the zodiac.
