Last bus to shenzhen and last entry(Immigration) to Zhuhai From Macau

Can you please let me know what time does the immigration entry closes at ZH ? (I am going from Macau to ZH during the late evening and then taking a bus to Shenzhen during the weekdays)
Then after passing through the immigration at ZH, where do I take a bus to go to Shenzhen and what time will be the last bus to Shenzhen? Thank you for helping me...
