Policy 1: We encourage you to make all experimental data in your article publicly available. If data cannot be made public due to confidentiality or sensitivity reasons, please explain this at the end of the article.

Policy 2: We strongly encourage you to make the supplementary data of the research publicly available as soon as the article is published, and to comply with relevant legal and ethical regulations as much as possible.

Policy 3: We encourage you to provide as much basic data from your article as possible (without compromising the privacy of other participants in the study). If this is not possible, at least provide the minimum data necessary to support the conclusions drawn in the article.

Data should not be shared in any way that could compromise the privacy of research participants. If data sharing would require authors to violate any law or licensing agreement, the data should not be shared. If the data used is licensed from a third party, the data availability statement should explain how permission to access the data can be obtained.

If a specific research community has established standards for the content, location, and method of data sharing, we expect authors to meet these standards.

Although data sharing is not mandatory in most journals, Journal of China & Foreign Highway reserves the right to request important data for your article at any time, so that the reproducibility of the paper's results can be verified.

How to Obtain Data as Required

Data requestors should do the following:

1. Send an email to the corresponding author of the paper requesting the relevant materials.

2. The journal will evaluate the request and, where appropriate, encourage the authors or their institutions to share the data, but Journal of China & Foreign Highway does not mandate data release.

3. Where appropriate, invite the original authors to participate in re-analysis.

If no reply is received from the corresponding author after one month, please send an email to the journal's editorial office.
