Gold plays a zodiac every other year.

The gold of the coming year is the Zodiac Tiger.

The gold in the next year is a two-part allegorical saying, which means that the gold in the next year is not as valuable as the copper coins now. In the Zodiac, the tiger in the Zodiac is fierce when he is young, but as he grows old, he declines, just like gold can't match copper in the next year, and his abilities in all aspects are reduced, and he may not even be as brave as other animals. Therefore, the gold in the coming year represents the zodiac tiger.
