How many days does the express delivery from Shenzhen to Shandong usually take?

Mainly depends on where it is sent to Shandong!

One-day tour of provincial capital-municipality directly under the central government

Provincial capital-a day in the provincial capital

Provincial capital-non-provincial capital city for two days

Non-provincial capital-within three days of non-provincial capital

Note: Shenzhen is a city under separate state planning, with the same speed as the provincial capital.

My past experience is:

Surface mail usually takes at least 7 days and at most 15 days.

Express delivery takes 2 days at the earliest, usually 3 or 4 days, which is safer.

EMS takes two days at the earliest, which is similar to express delivery and the safest.
