Jockey Club’s four-character poem, what zodiac sign do the three and six together refer to?

The Jockey Club’s four-character poem refers to the four numbers drawn by the Hong Kong Jockey Club in each issue and is used for lottery betting. The "three-six combination" refers to the combination of numbers ending in three and six to form a lottery ticket. It does not represent a certain zodiac sign. The zodiac refers to the animal symbols in the twelve zodiac signs, including rat, ox, tiger, rabbit, dragon, snake, horse, sheep, monkey, chicken, dog, and pig. In the Jockey Club Lottery, there is no necessary connection between numbers and zodiac animals.
