Visitor pattern is suitable for systems with relatively stable data structures. It disconnects the coupling between data structures and operations acting on structures, allowing the set of operations to evolve relatively freely.10-15% of aquatic plants and hidden objects are planted shallowly at the edge of the pond to create an environment for lobsters to inhabit and shell and reduce mutual killing. The influence of water quality on lobster yield cannot be ignored. During the breeding process, the PH value of the pool water is kept between 7.5 and 8.5, and the transparency is 30-40cm. Fresh water should be added frequently, quicklime solution should be splashed regularly, water quality should be adjusted, and diseases and shelling failure should be prevented. 2. Feed feed reasonably. Lobsters will kill each other when hungry and under-fed, so the feeding amount must be sufficient. Lobster feed is animal and plant feed. Plant feeds are wheat, aquatic plants, rapeseed cakes, etc. Animal feeds are miscellaneous fish, miscellaneous meat, livestock viscera, etc. At ordinary times, the feeding time, feeding amount and feeding method are determined according to the habit of lobsters falling in the day and coming out at night and the density of lobsters in the pond. 3. Scientific fishing. Young shrimps can grow to commercial specifications in 60-90 days under the condition of suitable temperature and sufficient feed. The seedlings will be released in March and will be caught in rotation around June, selling large ones and keeping small ones.　　为解决问题，莲生在朋友洪善卿和汤啸庵的陪伴下来找小红，被小红伶牙利齿的女仆大骂一顿。朋友在窘境中撇下莲生径自离去，莲生只得独自去见小红。毕竟已有了四五年的感情，一番抚慰之后，二人又和好如初。李家厅堂里，大大小小、男男女女十几个孩子，足足围了三桌子。中年妇人追到的时候，正看到这一幕，先是一声长叹，不经意间潸然泪下。王穷点头道：微臣大伯母身体微恙，故而延迟了两日。林聪心中一动，点头道：原来是这样。
