Shēng Jí (升級; Advance in Level) is a family of point trick-taking card games played in China and in Chinese immigrant communities. They have a dynamic trump, i.e., which cards are trump changes every round. As these games are played over a wide area with no standardization, rules vary widely from region to region.

The game can be played with multiple decks of cards. With one deck, it may be called Dǎ Bǎi Fēn (打百分; Competing for a Hundred Points) or Sìshí Fēn (四十分; Forty Points); with two decks, as is most commonly played, it may be called Bāshí Fēn (八十分; Eighty Points), Tuō Lā Jī (拖拉機; Tractor), Zhǎo Péngyǒu (找朋友; Looking for Friends), and Shuāi Èr (摔二; Throw Two).

The article below mainly describes the Bashi Fen variant, with players playing with two decks and in fixed partnerships.

The game is played with four players in fixed partnerships, with players sitting across each other forming a team. Each team has a rank that they are currently playing, henceforth referred to as their score. At the beginning of a match, everyone starts at a score of 2.

The bansuri (Hindi: बांसुरी, Nepali: बाँसुरी, Marathi: बासरी, Assamese: বাঁহি, Bengali: বাঁশি) is a transverse flute of India made from a single hollow shaft of bamboo with six or seven finger holes. An ancient musical instrument associated with cowherds and the pastoral tradition, it is intimately linked to the love story of Krishna and Radha, and is depicted in Buddhist paintings from around 100 AD. The Bansuri is revered as Lord Krishna's divine instrument, and is often associated with Krishna's Rasa lila; mythological accounts tell of the tunes of Krishna's flute having a spellbinding and enthralling effect not only on the women of the Braj, but even on the animals of the region. The North Indian bansuri, typically about 14 inches in length, was traditionally used as a soprano instrument primarily for accompaniment in lighter compositions including film music. The bass variety (approximately 30", tonic E3 at A440Hz), pioneered by Pt. Pannalal Ghosh and elevated to heights of global renown by the brilliance of Pt. Hariprasad Chaurasia has now been indispensable in Hindustani Classical music for well over half a century. Bansuris range in size from less than 12" to nearly 40".
