Mainly because of the end of the first May Day, the whole tourism industry entered a small off-season and lasted until the summer vacation. Another is Hong Kong in May. The weather is hot, and some places in Southeast Asia have also entered the off-season. There are no big festivals in May, there will be no large-scale sales promotion, and there are fewer people sweeping goods. Mainly the above three aspects, personal understanding. For reference only.
