A fresh wind is blowing through the offices of the world's most widely watched TV weather forecast. Two new faces are joining CCTV-1's weather team after 11 years of unchanged operation. But the tweak in presentation has caused something of a storm among viewers.

Thirty-year-old Wang Lanyi and Feng Shu, 27, have joined Weather Forecast, a Chinese television institution.

The program, which starts at precisely 7:31 PM every night, first aired the year Feng was born.

Wang said her first hello to her new audience on the evening of June 25 and Feng on July 1.

It has become a long habit for Chinese families to watch CCTV-1's 7pm daily news (called Xinwen Lianbo in Chinese). Weather Forecast, which follows after a few advertisements, has become part of the habit too.

The anchors have become household names and are invited into the homes of hundreds of millions of people every evening. They become part of the family.

In 2007, the program scored the highest TV ratings in China, according to CTR Market Research.

A survey by CCTV says that in 2007, every night about 600 million people are watching the program.
