I hv a question appreciate some bros here can help. I will be landed at Macau airport ard 4.30pm and heading straight to ZH, I usually via gong bei but the traffic is heavy at this time due to peak hour, sometime takes 1.5 hrs to clear both custom. Someone told me it will be alot faster thru lang qin and from lang qin to gong bei by cab is only 15min. Is it correct, how much time I can save? thanks in advance.
