Context paragraphs:
Duck rice: Duck rice () is a Singaporean Chinese meat dish, made of either braised or roasted duck and plain white rice.  The braised duck is usually cooked with yam and shrimps; it can be served simply with plain white rice and a thick dark sauce; side dishes of braised hard-boiled eggs, preserved salted vegetables, or hard beancurd may be added.  In addition, Teochew boneless duck rice is a similar, but a more refined dish; due to the slightly tougher texture of duck, the duck is artfully deboned and sliced thinly for the convenience and ease of the diner, allowing the sauces to seep into the meat, making it a more pleasant experience on the whole; Hainanese chicken rice and other similar dishes have followed this style due to the popularity.

Every Second Counts (album): Every Second Counts is the fourth studio album by American rock band Plain White T's.  It is the first Plain White T's album to be released on Hollywood Records along with Fearless Records.  The album peaked at number 10 on "Billboard" 200 on July 29, 2007, and was certified Gold by the RIAA in October 2007.  "Every Second Counts" peaked at number 3 on the UK Albums Chart.

Plain White T's: Plain White T's (read as "plain white tees") is an American rock band from Lombard, Illinois, formed in 1997 by high school friends Tom Higgenson, Dave Tirio, and Ken Fletcher.  They were joined a short time later by Steve Mast.  The group had a mostly underground following in Chicago basements, clubs and bars in its early years.

White label: White label records are vinyl records with plain white labels attached.  There are several variations each with a different purpose.  Variations include test pressings, white label promos, and plain white labels.

Big Bad World: Big Bad World is the fifth studio album by American rock band Plain White T's.  It was released on September 23, 2008 by Hollywood Records.  The creation of this album was a follow up album to "Every Second Counts" in hopes of breaking free from being the "Hey There Delilah" Band.  To promote the album, the Plain White T's launched a few webisodes, which together form the series "Meet Me in California".  The majority of the album was written while on the road, in planes, in hotels, and on buses.

All That We Needed: All That We Needed is the third studio album by American rock band Plain White T's.  This is also Plain White T‘s second album with Fearless Records.  In July 2007, after the release of "Every Second Counts", the song “Hey There Delilah” was re-issued as a single and sold unexpectedly well, hitting #1 on the Billboard Hot 100.

Plain Yellow Banner: The Plain Yellow Banner was one of the Eight Banners of the Manchu Qing dynasty military.  The Plain Yellow Banner was one of three "upper" banner armies under the direct command of the emperor himself, and one of the four "right wing" banners.  The Plain Yellow Banner was the original banner commanded personally by Nurhaci.  The Plain Yellow Banner and the Bordered Yellow Banner were split from each other in 1615, when the troops of the original four banner armies (Yellow, Blue, Red, and White) were divided into eight by adding a bordered variant to each banner's design.  After Nurhaci's death, his son Hong Taiji became khan, and took control of both yellow banners.  Later, the Shunzhi Emperor took over the Plain White Banner after the death of his regent, Dorgon, to whom it previously belonged.  From that point forward, the emperor directly controlled three "upper" banners (Plain Yellow, Bordered Yellow, and Plain White), as opposed to the other five "lower" banners.
