Cha Nae (จะแหน) is a subdistrict in Saba Yoi District, Songkhla. The district's agricultural plan records five villages in the tambon.
Ban Muni is associated with the locally distinctive seedless champedak known as To Yawo. A government account explains that the fruit was named after its grower and became recognised for its small or undeveloped seeds.
The Saba Yoi agricultural office continued supporting local champedak cultivation in 2026, including a demonstration plot and irrigation advice. This fruit-growing identity belongs to the communities within Cha Nae; it does not mean orchards operate as public attractions. This Songkhla tambon is distinct from Chanae District in Narathiwat.
