It should be a liar. After all, there are very few people here in Guangzhou who are trained first and then employed. Generally speaking, experience is required, or new people are recruited, and then training is conducted after joining the job (some of them are trained first, and training is also considered introductory and paid). Although you don't rule out training before employment, as you said, you should not be in Guangzhou yourself, so it's better not to go.
