Care must be taken, however, in distinguishing between an offer and an invitation to treat.
要注意的是,无论如何,应当区分出协议中的要约和要约邀请.
以下英文仅供参考：
nvitation to treat
There are "invited bidders to do business," "consultation invitation", "solicitation" and "asked people to bid" means.
Invitation to treat: an invitation, not a valid offer. For example, published in newspapers of general advertising, mailing tender, auction notices, and send price lists and catalogs, are not an offer.
offer

offer: an offer is made a party to the other party to contract conditions. Hope someone can fully accept that the meaning of this condition. An offer of a party called the offeror, the party called Upon receiving the offer by the offeror.
The difference between an offer and an invitation:

附 另外一简单回答：
“Invitation to treat” does not have binding force to the person who is giving it to another person,. E.g. advertisement, price displayed on the shop-window. This is an “invitation” to another person to make an offer to contract. A buyer may make an offer; the seller may reject that offer.
On the contrary, an “offer” must be clearly made and direct approach to another party to contract; it is an expression of willingness to negotiate. Thus, the person make an “offer” is intending to be bound.
These two concepts not only have been applied in common law, but also in German civil law system. I hope my explanation can really help you.
中文来说,“Invitation to treat”是要约邀请,是希望他人向自己发出要约的意思表示.如寄送的价目表、拍卖公告、招标公告、招股说明书、商业广告等为要约邀请.
而“offer”则是要约,与承诺相对应,依合同法第十四条的规定,要约是希望和他人订立合同的意思表示.其构成要件主要有：内容具体确定；表明经受要约人承诺,要约人即受该意思表示约束.
二者的区别明显：其一,效力不同.要约对要约人具有约束力,而要约邀请则无；其二,要约以订立合同为直接目的,受要约人承诺送达,合同即告成立.要约邀请,则不是以订立合同为直接目的,它只是唤起别人向自己作出要约表示或使自己能向别人发出要约；其三,要约必须包含能使合同得以成立的必要条款,要约邀请则不是；其四,要约一般是针对特定的对象进行,而要约邀请的对象则一般是不特定的大众对象.
