This is the question that decides whether a system imported from China survives contact with a real overseas dining room. The owner grew up reading Chinese and wants the margin report in Chinese. The server hired locally reads Spanish, Vietnamese or Khmer and nothing else. If the software can only be in one language at a time, somebody is guessing all day.
Language belongs to the account
In MiYaDine the interface language is set on the user account. Log in as the owner on the office machine and the whole interface is Chinese; log in as a server on the floor tablet and the whole interface is in the local language. Both are looking at the same tables, the same open bills and the same stock — only the labels differ. Nothing has to be installed twice, and there is no separate “English edition” to buy.
That matters more than it sounds. It means you can hire a local server on Tuesday and have them working the floor on Wednesday without teaching them a single Chinese character, while you keep reading your own reports the way you always have.
The dish is one record with two names
Behind the scenes there is one dish record. It carries a Chinese name and a local-language name, and every screen picks whichever one fits the user looking at it. Change the price once and it changes for the counter, the QR ordering page and the printed receipt at the same time, because all three are reading the same record. You are not maintaining two menus that slowly drift apart.
The same pairing carries through to the kitchen. The floor can order in the local language while the kitchen ticket comes out in Chinese, or in both — see kitchen and front of house in different languages.
Which languages, and where the limit is
23 languages ship with the system, including the ones most often missing from Western POS products: Thai, Vietnamese, Indonesian, Malay, Japanese, Korean and Arabic alongside English, Spanish, French, Portuguese and Italian. Currency symbols and non-Latin scripts also survive the thermal printer — that is a separate mechanism, explained in why the receipt prints boxes.
One honest limit: our human support team works in Chinese. The software speaks 23 languages; the person on the other end of WeChat speaks Chinese. For a shop where the owner is the one who calls support, that is usually the right trade — but it is worth knowing before you buy rather than after.
