The crew traveled with Yuan for over half a year to catch some rarely seen moments for the 40-minute episode.

The footage reveals Yuan is not only a globally celebrated agriculture expert but also a romantic husband and a caring grandfather.

In the opening scenes of the first episode, which is devoted to Yuan, his three granddaughters recall stories about their grandfather and say that he's most concerned with their English and math studies.

The grandkids recall that when Yuan traveled to Hong Kong with his family, he tried to buy his wife a new watch but didn't because it was too expensive, and he fed his wife a hawthorn candy.

"Yuan's children and grandchildren usually gather for dinners at his home during weekends and holidays," says Lai Zhangping, another director, who was in charge of the episode.
