【NEW】 The Yuelai Inn
The Explore page now features a 3D inn in ink-painting style. Guests raise their cups in the hall, others turn the millstone and draw water in the courtyard, and waiters bustle through with trays.
And the guests at the tables are real historical figures. A new group arrives at random each time you open the page, and you can tap the refresh button to welcome a different crowd anytime.
Point at someone with the pointer to read their story from that year, along with the people and events connected to them.
【Map】
· Smoother scrolling on the year ruler and faster year switching
· Corrected territorial borders for several periods, including the Tang, Wu Zhou, Tibet and Northern Song
【Other】
