Can you translate official or legal documents?
No. Sworn translation, contracts, court work and medical documents are not offered here, and Portuguese authorities usually require a certified translator for them anyway. What is offered is spoken help in the room.
How good is your Chinese, honestly?
HSK 4, score 210, plus study in Hubei and the Chinese Bridge competition. Solid everyday level: enough to explain what is being asked and to catch a misunderstanding. Not a conference or legal interpreting level.
Which languages, in which direction?
Portuguese native, English fluent, Chinese as the bridge. In practice: Portuguese to Chinese, Portuguese to English, English to Chinese — whichever combination gets us through the appointment.
How far in advance should I ask?
A few days if you can. I teach in the evenings, so I take a small number of jobs and the good slots go first. If it is urgent, still write — sometimes it works out.
Do you go outside Lisbon, Oeiras and Cascais?
Sometimes, with transport at cost on top of the hourly rate. Sintra and Amadora are usually fine. Ask and I will give you a straight yes or no.
Is machine translation not enough?
Often it is, and I will say so. Where it reliably fails is formality, Portugal-versus-Brazil vocabulary and rental terms like caução or condomínio. I wrote that out in Portuguese here, with the phrases worth carrying on your phone.
Can you also teach me Portuguese?
That is the main job, yes — Brazilian Portuguese, in the evening, online or in person. Lessons and prices are here. Teaching happens in English, not in Chinese.
