These three little figures are from the Changsha kilns, from southern China. They were made in the Tang dynasty, 618 tot 907.

The middle one is a fish-shaped whistle. It still works when blowed, and was possibly made as a toy. The little loop handle is broken.

The body on the whistle is greyish, and on the other two pieces more yellowish-brown.

The piece on the right is probably a scroll weight. It is shaped as a turtle,and has a loop handle.The brown glaze is crazed, and simply resembles a tortoise-shell.

The one on the left was probably a scroll weight too. It is shaped as (probably) a carp. The tail is damaged, so is the loop. Scroll weights hung on a hanging scroll to keep it from rolling up.

Mostly these pieces are described as toys, but that is probably not entirely true.
