Visitors continue flooding to Tokyo’s Ueno Zoo to have a peek at the pandas on Feb. 1, 2018. /CFP Photo

Hundreds lined up outside the zoo from as early as 5 am on Thursday to be in with a chance of seeing the first general public appearance of seven-month-old panda cub Xiang Xiang. /CFP Photo

Xiang Xiang was allowed to see a limited number of visitors with tickets a month and a half ago. Those tickets were won in a lottery. /CFP Photo

The cub is so popular that she has to work an extra two hours per day between Jan. 23 and 31. However, the panda-lovers themselves are only allowed to stay for one or two minutes in order to give everyone a look. /CFP Photo
