The amount of uncle's first meeting gift to niece varies due to regional and cultural differences, kinship and income level. Generally speaking, meeting gifts should be moderate, which can not only show uncle's sincerity and respect, but also not make niece feel too burdened. In some areas, when they meet for the first time, uncles will send a certain amount of red envelopes filled with cash or physical gifts, such as gold, jewelry or expensive watches. The value of these gifts ranges from several hundred yuan to several thousand yuan, depending on the specific situation. If the niece's family is rich, the gift money can be increased appropriately, but it should also be considered that too much gift money may cause discomfort to the other party. Of course, in some regions and cultures, the amount of gifts given by uncles may be slightly higher, or even more than 10,000 yuan, but this is only a special case and does not represent the general situation.
