On "personal tailor" and "Private Customization" —— Literally, the main difference between Xiaoyu's private customization and private customization lies in "Ding" and "Ordering". In order to better understand "personal tailor" and "private ordering", we need to distinguish between "ordering" and "ordering" at first. For example, some contracts are agreed to take effect on the date specified in the contract, so not all contracts take effect from the date of signing. From the example, we can know that "setting" means "decision" and "confirmation". And "order" is a promise expressed in good faith in advance. We can understand "personal tailor" and "Private Customization" from both macro and micro aspects. On the macro level, there are special services according to individual needs. At the micro level, ordering food generally means ordering what you already have, such as ordering food before a party or banquet, and generally ordering food that you will like or may need according to the menu. On the other hand, customization is unprecedented. Services are specially prepared for individuals, such as customizing clothes. Generally, clothes are made for that specific person according to personal waist circumference, chest circumference and other parameters. Customers need to pay the labor and material costs of clothes paid by the store, including the cost of keeping clothes. After payment, the goods belong to the customer. Ordering clothes is renting clothes, which means that it will only be used for a period of time and will not be preserved for a long time. Ordering clothes usually means paying for temporary misappropriation of clothes. The expenses include not only the time occupied by clothes, but also the depreciation of clothes and the accidents that may occur during the use of clothes, that is, "life insurance" (citing life insurance). Now, because of the use of the Internet and people's neglect of Chinese character learning, the difference between "customization" and "customization" has been ignored, and only its macro significance is known.
