Hi, I am intending to bring my filipino helper with me to Macau, enter China thru Zhu Hai, go over to Hong Kong from Zhu Hai, and then back to Zhu Hai, lastly back to Macau and flight back to Singapore.
Is there a need for my helper to get a visa or mutiple visa?

Trip is as below :
Singapore - Macau - Zhu Hai - Hong Kong - Zhu Hai - Macau - Singapore
