When the official homepage shows「主办单位 / 承办单位 / 协办单位」, the first question is not “who has the most power / who issues tickets?” — it is: how do those three official label lines read, and will this site invent phones, WeChat IDs, or a fourth host? This post only teaches how to read those three lines. It does not rewrite the “what is the exhibition” essay, and it is not an organization directory. For positioning and edition background, see What is CDYPE / the 19th edition?.
CDYPE AI on www.cdype.ai is an unofficial third-party assistant, not the organizer’s website or official support. Exhibition information and registration entry points are subject to http://dongying.banshanlvtu.com/. Registration is only on the official site.
Three verified facts to pin first

The three official label lines — restate, do not upgrade
The wording below restates what is visible on the official homepage (checked by this site on 2026-09-22). Read only the three official label lines. This site will not invent phones, emails, WeChat IDs, or contract details, and will not upgrade a footer © line into a fourth host role.
Official three lines (restated verbatim):
主办单位：东营市东营区石油装备行业协会、东营市石油业商会
承办单位：北展东方(北京)国际会展服务有限公司
协办单位：东营米兰奥特莱斯小镇
| Label you see | Correct reading | What this site will NOT invent |
|---|---|---|
| 主办单位 (host) | The official page lists two bodies on the host line: 东营市东营区石油装备行业协会 and 东营市石油业商会 | No ranking of “who is bigger”; no contact numbers or service windows |
| 承办单位 (organizer / undertaker) | The official page places 北展东方(北京)国际会展服务有限公司 on the 承办 line | Do not rewrite it as “the only host”; a footer © with the same name is still not an extra 主办 label |
| 协办单位 (co-organizer) | The official page places 东营米兰奥特莱斯小镇 on the 协办 line | Do not upgrade into “official partner” marketing language; invent no hotel packages, badge/ticket issuance, or ticket channels tied to that name |
One-line alignment: whichever label line the official site writes, this site restates that line — stop at the label wording. No invented role ranking, no invented external contacts, and no stretching「协办」into a partnership promise beyond that label.
How short name, CDYPE, and the full name map already has its own post: CDYPE name aliases: full name, Dongying short name, and how they map. This post does not re-list the alias table, so the two articles do not cannibalize each other.
Easy mix-ups (reading these three lines only)
- 主办 ≠ 承办 ≠ 协办. Three different labels — do not flatten them into “all hosts” or “one office for everything.”
- Footer © naming 北展东方 ≠ a fourth host. A copyright credit is not the same label as「主办单位」; this site will not promote the footer as an extra host.
- 协办 ≠ inventable “official partner / hotel package.” The co-organizer line stops at the official wording; this site invents no Milan-tied lodging packages, ticket channels, or badge-issuance ownership.
- An organization name ≠ a contact directory. Seeing an association, chamber, exhibition company, or town name does not mean this site holds or publishes phones, emails, WeChat IDs, or contracts.
- Do not rank authority beyond the three labels. This site restates the label wording only — it does not draw an org chart of who “decides.”
What this site can and cannot say
| This site can say | This site will not invent |
|---|---|
| Restate the official 主办 / 承办 / 协办 lines and the organization names on them | Phones, emails, WeChat IDs, contract terms; who issues badges or tickets; hotel packages tied to 米兰 |
| Note: footer © is not a fourth「主办单位」label | Upgrading 承办 or © into「主办」; upgrading 协办 into “official partner” beyond the label |
| Dates, venue name, official URL | Opening hours, ticket prices, shuttles, parking |
| Mark unknowns as “check the official site”; help you check whether a sentence matches the official labels | Exhibitor roster, forum agendas, fees and deadlines; claiming this domain equals the organizer’s website |
Shortest action order for you
- Open http://dongying.banshanlvtu.com/ and locate the three lines「主办单位 / 承办单位 / 协办单位」; compare them with the restatement above.
- When you cite externally: mark the source as official label lines, keep the literal 主办 / 承办 / 协办 wording and organization names — do not rewrite roles or add unpublished contacts.
- Dates and venue still follow the live official page; verification path: “How to verify official information” above.
- If you only want to reconfirm “are these still the official three lines / will this site invent phones or a fourth host,” ask on the English home. The assistant will not invent contacts or role rankings. Chinese home: /.
- To register: use only the official 参观登记 (visitor registration) / 参展报名 (exhibitor registration) entry points.
Short FAQ
Are host, organizer, and co-organizer the same body?
No — not the same label. The official page writes three lines: two hosts listed together, one 承办 body, one 协办 body. When you cite externally, keep each label on its own line; do not merge them into “all hosts.”
The footer names 北展东方 — is that another host?
No. The footer © credit you see is not the same label as「主办单位」. This site will not upgrade © into a fourth host.
Can the co-organizer line be written as “official partner”?
When you cite externally, this site only restates the「协办单位」label wording. It will not invent “official partner” marketing language beyond that label, and will not invent lodging packages or ticket channels tied to it.
Can you give me phones or WeChat for the association / chamber / exhibition company?
No. This site does not hold, invent, or publish those contacts. When you need a service entry point, return to the official site for the live registration paths.
Who issues badges or tickets?
This site will not invent badge or ticket issuance ownership for you. Follow the live official site wording and on-site arrangements; this site is not a badge desk or ticket window.
How does this post split work with “what is CDYPE”?
If you need positioning, edition, and background, use “What is CDYPE / the 19th edition?” above. This post only covers how to read the official 主办 / 承办 / 协办 lines, so the two articles do not rewrite each other.
I can read the three lines — where do I register?
Return to the official site for 参观登记 (visitor registration) / 参展报名 (exhibitor registration). This site cannot complete registration for you; the final basis remains http://dongying.banshanlvtu.com/.
You now have a reading card: the official 主办 / 承办 / 协办 lines are restated literally — no invented contacts, no authority ranking beyond the labels, no fourth host from footer ©. To reconfirm “is this still the official wording” or this site’s identity out loud, ask the assistant on the site home. The final basis remains http://dongying.banshanlvtu.com/.
