2.14. GENERAL ASSEMBLY NEWSPAPER

The IAU XXVIII General Assembly daily newspaper 天問 or “Inquiries of Heaven”, will be published during the

GA in ten editions. The name of the newspaper was chosen after the poem “Inquiries of Heaven (IH)” (天問) by

Yuan QU, a Chinese poet, in 310 B.C. He raised more than 150 inquiries about the Universe and society in

"Inquiries of Heaven," and described humanity's early thoughts on the Cosmos. At the beginning of the poem, Yuan

QU asks about the remotest past of the Universe with his profound thoughts[1]:

Whoever has convey‟d to us 曰:邃古之初，

Stories of the remotest past? 谁传道之？

Who can verify the shapeless 上下未形，

Beginning time has overcast? 何由考之？

Who can confirm the world had been 冥昭瞢暗，

A mass without darkness and light? 谁能极之？

If th‟ universe was but chaos, 冯翼惟像，

What evidence is there in sight? 何以识之？

And then, how was it arranged 明明暗暗，

That, there came to be Night and Day? 惟时何为？

„Mongst th‟ yin, th‟ yang and th‟ either that make 阴阳三合，

Things, th‟ vital role which one does play 何本何化？

Chinese tell an incredible love story during Qixi Festival:

A young cowherd (Niulang) came across a beautiful girl, the seventh daughter of the Goddess (Zhinü), who just had

escaped from boring heaven to look for fun. Zhinü soon fell in love with Niulang, and they got married without the

knowledge of the Goddess. The Goddess of Heaven was furious to find out that Zhinü had married a mere mortal

and ordered Zhinü to return to heaven. On Earth, Niulang was very upset that his wife had disappeared. Suddenly,

his ox began to talk, telling him that if he killed it and put on its hide, he would be able to go up to Heaven to find

his wife. Crying bitterly, he killed the ox, put on the skin, and carried his two beloved children off to Heaven to find

Zhinü. The Goddess discovered this and was very angry. Taking out her hairpin, the Goddess scratched a wide river

in the sky to separate the two lovers forever, thus forming the Milky Way between Altair and Vega.
