After six years in Cambodia, did you go back to China Customs for questioning?

After six years in Cambodia, I need to ask questions when I return to China Customs. According to relevant public information, they have lived in Cambodia for six years, so when entering and leaving the customs, they will definitely ask some questions, such as the purpose, the length of time, and whether they have brought anything in. Auditors will ask them if they have worked, studied or lived in Cambodia. They will also ask for a Schengen visa six years ago, travel documents in Cambodia and family photos for verification.
