Every home, every shop, every Western-style café in Vietnam has a small altar somewhere — even if it's just a framed photo with incense. The bàn thờ (ancestor altar) is the spiritual centre of Vietnamese domestic life. Pick your situation and we'll tell you the right behaviour, when to bow, and the photograph rule.
Most tourists notice the bàn thờ and don't know what to do. Some photograph it (offence). Some ignore it (acceptable). Some bow (correct, if observed). The altar is not a decoration — it's a real spiritual anchor, with incense burned morning and evening, offerings on mùng 1 (1st of lunar month), Tết, and rằm (full moon). This widget tells you what's right for your specific situation: homestay stay, friend's home, market stall, or Tết visit.
The two key rules: photograph = ask first, default NO. Entering a home = small bow toward the altar. That's 80% of what you need to know.

The one thing people miss

Every home has one. Even Western-style apartments, even modern minimalist cafés, even beachside bungalows. The bàn thờ may be tiny (a shelf with a photo and incense) or elaborate (a full wooden altar with candles, fruit, and offerings). It almost always faces the front door or the kitchen — symbolically the most important axis of the home.
Incense morning + evening. Most households burn incense twice a day — once in the morning, once in the evening. The smoke is the connection to the ancestors. If you walk into a home in the morning and smell incense, that's the morning offering just finished. Don't blow it out, don't wave the smoke away.
"Mùng 1" and Tết are big offering days. Mùng 1 (1st day of lunar month) and rằm (15th day, full moon) are the two monthly offering days — slightly bigger than daily incense, with fruit and small food offerings. Tết (Lunar New Year) is the big one — full family gathering, large food offering, new photo or decoration on the altar.
Photograph rule. Always ask. Default NO. Most Vietnamese will politely decline a photo of their altar. The altar is for the ancestors, not for social media. If you ask, accept the no gracefully. If they say yes, take one photo, no flash, and don't post it without their explicit permission.
When to bow. Bow slightly when entering a home with a visible altar — a small nod of the head is enough. Bow slightly when leaving a room where the altar is in view. Bow more deeply (with hands at sides) if you're a guest during Tết or if the family is praying. Don't bow at random — only when entering, leaving, or when the family is engaged.
The "rằm" (full moon) twice-month ritual. Rằm is the 15th day of each lunar month — when the moon is full. Mùng 1 is the 1st day. Together they form the twice-monthly worship cycle. Many shops close briefly on rằm, families gather for dinner, and the offerings on the bàn thờ are more elaborate than weekday evenings.
Incense + burner
The core. Always burning or recently burned. Smell is part of the experience.
Photo of deceased
Framed, often black and white. Multiple generations sometimes.
Fruit offering
5 fruits (ngũ quả) for the five elements. Oranges, apples, bananas are standard.
Votive money
Yellow paper money, burnt in a small burner. Symbolic for the afterlife.
If you're in a friend's home and the altar is in the background, just don't post that photo. If the family notices, apologise simply and delete in front of them. It's not a confrontation moment like a funeral procession — most Vietnamese are understanding of accidental photography.
Yes, for first visits. Fruit, sweets, or a small wrapped item. Avoid black or white wrapping (mourning colours). Red, gold, and pink are appropriate. Don't give knives or clocks (associated with severing relationships or ending time). Wine or beer is fine for a casual dinner invitation.
If you're a guest in a homestay and the incense smoke triggers allergies or breathing issues, mention it to the host privately. They may move the incense to a more ventilated area, or burn it less often. Don't complain about the incense practice itself — it's the spiritual heart of the home.
Only if invited. Most Vietnamese would find it strange for a foreign guest to light incense without being asked. If you want to participate, ask the host: "Tôi có thể thắp hương không?" (toy ko theh tup huong kohng, "Can I light incense?"). If they say yes, light 1 or 3 sticks from the communal candle, place, bow slightly.
Ancestor Altar Awareness is a Vietnam Compass standalone tool. It exists because the bàn thờ is everywhere in Vietnam and most tourists don't know what to do. The decoder runs in your browser; nothing is sent anywhere.
Limitations. Local practice varies. Catholic and Buddhist families have different altar conventions. Use the guide as a starting point and follow the host's lead.
Data collection. None. This tool is a single HTML file. The decoder runs entirely in your browser — no inputs are sent to any server, logged, or stored.
