It's usually someone that both parties know. After determining the engagement date through communication, the middleman will usually take the man's parents to the woman's house to discuss the details such as bride price, banquet and wedding candy, and then set a date to go to the woman's house for the bride price. These days, it is generally agreed by both parents.
On the day of engagement, the groom-to-be usually wears an engagement ring, as well as gifts (usually depending on family conditions, the amount of gifts is different, and some lucky numbers are usually selected), two red bags, two red belts, two sets of clothes (including a cotton-padded jacket inside the clothes), and the so-called small six kinds, including (six pounds of meat, six scaly fish, six bottles of wine and six boxes of sugar). There are also six boxes of snacks), in which the woman will return two copies of each kind to the man's family except meat. The woman's family also needs to prepare something, and the woman should prepare a pair of new shoes for the man, which is also commonly known as husband's shoes.
The rest is that the woman's family will prepare tea and fruit snacks to entertain relatives and friends, find a good emcee to adjust the atmosphere on the day of engagement, let everyone chat together, and then invite the man and the middleman to a good hotel for dinner. After dinner, the man will give the woman a red envelope and press the table. When leaving, the woman will give back five kinds of meat, two copies of each, and part of the down payment as a gift to the man. Then the man should leave soon, and the two sides can't say goodbye to each other when they leave.
