Many sub-ethnic groups among indigenous tribes in Sabah and Sarawak live in rumah panjang (longhouses) and maintain their traditional spiritual/animistic beliefs. When visiting a longhouse, a few do's and don'ts have to be observed. These differ slightly from one group to another, but most share a common thread.

For example, it is believed that bad luck would result if a visitor enters a new longhouse while it is being constructed. Walking under a longhouse is also considered taboo. Never do so lest you be thought of as uncouth or ill-intentioned.

One should also never enter a longhouse without an invitation. The visitor should make his presence known by calling out from the bottom of the steps and after he is invited in, to leave his sandals or shoes outside before entering.

Once inside the longhouse, he should immediately make his way to the elder’s room to announce his presence and state his business. Never enter the sleeping quarters of a family without prior consent.

Walking within the longhouse also has its restrictions and rules. Visitors must tread lightly, ensuring that they never walk over a person.

When leaving, visitors are required to partake in a local wine (usually made out of fermented rice), or stop for a chat; as it is believed that visitors who do not pause will take away the wealth of the house with them.
