PBS devotes three nights and six hours to “The Story of China” (7 p.m. and 8 p.m.).

Host and historian Michael Wood has been traveling for more than three decades to the fast-changing country, and he insists that understanding China’s past is the key to comprehending the culture and economy that will have a crucial impact on the unfolding 21st century.

“The Story of China” offers a survey course in the dynasties, poets, painters and warriors that have defined China since the era of the Shang Dynasty, some 1,500 years before the Christian era.

Any documentary effort, even one six hours long, will seem like only scratching the surface of a story 4,000 years in the making. For that reason, the series has created a companion website www.pbs.org/storyofchina offering behind-the-scenes content, a timeline of China’s dynasties and even a game to learn the Shang language.

  • “Real Sports With Bryant Gumbel” (9 p.m., HBO, TV-PG) reports on the decline of bullfighting in Spain. This extreme sport was once seen as a high art and revered in Spanish culture and celebrated by writers including Ernest Hemingway. But its ritualized blood sport has increasingly alienated the country’s young, who see little to champion or celebrate.
  • The desert island comedy “Wrecked” (9 p.m., TBS, TV-14) returns for a second season. For the uninitiated, “Wrecked” pretty much plays “Lost” for laughs in the way that “Lost” turned “Gilligan’s Island” into a cosmic head-scratcher.

While “Gilligan’s Island” was derided as dumb escapism, it offered a neat microcosm of mid-century American society. Just singing the theme song gave you a rundown of class structure from movie stars and millionaires to “the rest.”

In contrast, the folks on “Wrecked” are pretty much cut from the same clueless cloth. Played by a large ensemble cast of comedians, they’re often seen whining about lost iPads and missing detergent. This season they contend with pirates.

  • The Bordelon siblings move on as the melodrama “Queen Sugar” (9 p.m., OWN) enters its second season.
  • The documentary “Cast From the Storm” (8 p.m., Fuse) looks at an Australian program for refugees.
  • TV-themed DVDs available today include “Under the Dome: The Complete Series.”
