旅 [lui21] is a common morpheme in modern Chinese.  Meaning travel,  旅 is a component of compound words such as 旅行 travel, 旅馆 hotel, and 旅伴 traveling companion. It is a military unit when used alone as a monosyllable noun -- usually translated to brigade. Another popular usage of late is +之旅 i.e. 台山之旅 a trip to Taishan, a usage (re)imported from Japanese.

In Taishanese, 旅 is the equivalent of the English verb go, corresponds to 去 in Mandarin and Cantonese.  In most cases, 去[hui33] can be used interchangeably with 旅, reflecting the Cantonese/Mandarin influence.

旅 is also a preposition of direction (i.e.  to in English), and used with verbs such as 走 go, 行 walk, 上 go up, 落 go down, 返 return, 出 go out, 入 go in, etc.
