Uchungechunge lwe-RA lwebhokisi lokuhlangana olungangeni manzi lunokusebenza okuthembekile kokuvala, okungavimbela ngempumelelo umswakama, uthuli, nokunye ukungcola ukuthi kungangeni ngaphakathi kwebhokisi lokuhlangana, ngaleyo ndlela kuvikelwe izinto zikagesi ezisebhokisini lokuhlangana emonakalweni. Ifanele izimo ezihlukahlukene zasendlini nezangaphandle, njengezindawo zokwakha, izinhlelo zokukhanyisa zangaphandle, izinto zikagesi, njll.
