Is it "Libra" or "Libra" in astrology? Is it pronounced ping or cheng ?

This sign should be pronounced "Libra", note the difference between "ping" and "cheng", Libra in English, for the following reasons.

1, the word comes from Greek life, think about it, what is the symbol of balance and justice? It's a ping, which can be used in physics tests.

2, Google search Libra image, also are the physical test in the scales. When translated, Libra should be translated as Libra.

3, and for those who insist on reading Libra (cheng), what is Libra? What's the scale in the sky? If that's the case, why aren't the other constellations called "Taurus", "Sagittarius", "XX" or whatever?

4, using google translate, Libra is Libra and Scale is Scale. I don't need to explain anything else
