The two newly arrived giant pandas at Ueno Zoo in Tokyo have been named, the Tokyo Metropolitan Government announced Wednesday. "Ri Ri" and "Shin Shin" were chosen from 40,438 suggestions sent in by the public.

The pandas, which arrived at the zoo Feb. 21, will go on public display at 1 p.m. March 22, the metropolitan government added.

The male, Ri Ri, was called Bili in China, while the female, Xiannu, was renamed Shin Shin. The two kanji characters for Ri Ri stand for power. Shin Shin means truth or genuine.

Of the more than 40,000 names sent in, Tan Tan and Mei Mei were the most popular.
