Hi, me(Singapore Passport) and my partner(Thai Passport) will be going to Zhu Hai(China) in November via Macau and then back to Macau for a couple of days for a holiday. Would me or my partner need to apply for visa for Macau and/or China before our trip? And since we're going to exit Macau on the day we arrive and come back a couple of days later, would that cause extra complication?
