China's outspoken Li Na on Friday said even a Grand Slam win wouldn't make tennis popular in her home country, as the public would forget all about it in just one month.

Li was speaking after beating Barbora Zahlavova Strycova of the Czech Republic 6-2, 6-1 to reach the fourth round, reviving memories of last year's bravura run to the semifinals.

Both Li and countrywoman Zheng Jie made the last four last year, the first time any Chinese player had done so at the Australian Open.
