Is it true that 2 yuan has 5 pairs of bone China chopsticks?

no.

Some are synthetic bone China chopsticks, which are much cheaper, ranging in price from tens of yuan. Real bone China chopsticks are expensive, ranging from 15 to 2, and none is less than 1, so the five pairs of bone China chopsticks in 2 yuan are not real.

Bone China is the abbreviation of bone China, which is a kind of porcelain made of animal bone charcoal, clay, feldspar and Shi Ying as basic raw materials, and fired twice by high-temperature plain firing and low-temperature glaze firing.
